it is funny to make that kind of exchanges, and they look nearly natural  ;)

Completely concur!

Inspired thinking going with the Peregrine engine and a Whirlwind canopy on your Shrew, aphophenia!

Thanks folks! Old Wombat: I'd love to see the Shrew in styrene  :smiley:

Supermarine Type 330 Scarab and Type 330F Scarabée

The Type 330 Scarab incorporated Vickers-Supermarine's notions for a simplified Spitfire structure. The straight leading-edge wing came directly from the cancelled Shrew. A new tail section was devised, incorporating straight-edged tail fin, rudder, stabilizors, and elevators. It was calculated that these changes would save up to 25 man-hours in construction time compared with the in-production Spitfire Mk.Ia fighter.

Other than its airframe changes, the Type 330 Scarab was essentially similar to the Spitfire. Matching mark designations were used. As such, the Scarab Mk.Ia was akin to the Spitfire Mk.Ia - being fitted with 1,030 hp Rolls-Royce Merlin III engines and 8 x .303 inch Browning guns. The Scarab Mk.II was like the Spitfire Mk.II in having a 1,175 hp Merlin XII.

Supermarine Type 330F Scarabée - What's the French for Dung Beetle?

French authorities had tested a Spitfire Mk.I and shown an interest. Supermarine then proposed a 'Francisized' version of the Scarab - the Hispano-powered Type 330F Scarabée. As planned, the Type 330F was to have a 1,280 hp Hispano-Suiza HS 12Z-89ter engine with 20 mm moteur canone. [1] Other than differences dictated by the engine change, cannon installation, and other French-supplied equipment, the Type 330F was essentially a standard Scarab.

Three Type 330F variants were originally proposed. These were known to Supermarine as the Type 330F-1 (as ordered, with DH propeller), the Type 330F-2 (substituting a Ratier 1606M propeller), and the Type 330F-3 (substituting a Chauvière 378 prop). A fourth type had to be added when the HS 12Z engine was unavailable - this was the interim Type 330F-0 powered by a 1,100 hp Hispano-Suiza 12Y-51.

In the end, the French were unable to provide even the HS 12Y-51 engines in any numbers. Only two Type 300 were provided to the Armée de l'Air - one standard RAF Scarab Mk.Ia (F-ASCA) for familiarization, and the sole Type 330F-0 Scarabée (F-ASCB). Neither aircraft seems to have survived the Battle of France.

______________________________________

[1] Standard Type 330F Scarabée armament was to be 1 x 20 mm HS 404 moteur canone plus four 7.5 mm MAC 1934 machine guns. All Type 330F sub-types could accommodate six wings but it is unlikely that the hard-pressed French ever mounted any number of wing guns in their two Type 330s.

I really like the temp markings on that export version!

I agree with Sir Brian.  You can see where the French roundel and rudder stripes will go, but there's nothing showing to spoil a civil registration.

Supermarine Type 332L Spectre

The RAF's Supermarine Type 332L Spectre fighter came about by accident. The original design was for a naval fighter for the Fleet Air Arm. This - the Supermarine Type 332 aka 332N with the proposed name of SeaSnake - was to be a lighter single-seat companion to Supermarine's proposed Type 333 twin-seat fleet fighter to Air Ministry Specification N.8/39. In the end, the Admiralty chose the Fairey Firefly to meet N.8/39 but ordered a test article from Supermarine for the single-seater.

A wing-damaged Scarab Mk.Ia was chosen for modification as the Admiralty's test airframe. The wing mounting points were moved aft to accept a new, single-spar wing with a 'Davis' airfoil profile. That spar was specifically devised to accommodate heavier-calibre armaments of Vickers design - specifically the Class 'F' .5-inch high-velocity machine guns [1] and the Class 'J' .75-inch autocannon. [2] With the autocannon not yet ready for service use, the initial proposals were either for four wing-mounted  Class 'F' guns or two Class 'F' HVs and four heavy machine guns (Vickers Class 'C'). [3] The Admiralty chose, instead, twin Vickers Class 'F' and four rifle-calibre Browning guns.

Rather than wait for trials, it was decided to place a pre-production order for Type 332s. Unfortunately, problems with the Type 332 test article conversion emerged almost immediately. Tests with carrier-style arrestor gear overstrained the airframe resulted in wrinkling to the rear fuselage. Supermarine suggested external reinforcement plates but, satisfied with its Grumman Martlets and Sea Hurricanes, the Admiralty was having doubts about the Type 332's suitability as a carrier fighter. The question was: What to do with pre-production order for Type 332s?

At this point, Club Run operations were underway to ferry combat aircraft ferry from Gibraltar to Malta. Ten operations had carrier-launched more than 300 RAF Hurricanes towards that embattled island. It was suggested that the RAF take over 'de-navalized' Type 332s for future Club Run operations to help relieve the Siege of Malta. This was quickly agreed and as the Type 332L Spectre fighters were completed, they were crated for delivery to Gibraltar. Re-assembled on 'the Rock', the first Spectre Mk.Is were prepared for the next Club Run - Operation Perpetual.

Between 10–12 November 1941, Operation Perpetual launched 40 Type 332L Spectres towards Malta. The aircraft were flown off HMS Ark Royal and HMS Argus. All aircraft were launched unarmed and with rear fuselage 'overload' fuel tanks installed. Two Spectres were lost enroute, another four were shot up on the ground before they could be armed and refuelled at RAF Hal Far. The survivors entered service with No.249 Squadron, RAF - some detailed to the grass strips at RAF Kalafrana [4] and RAF Ta Kali.

______________________________________

[1] The Vickers Class 'F' was a fixed, aircraft version of the 'HV' anti-aircraft machine gun adopted by the Royal Navy in 1929. Both types fired 12.7 x 120mmSR rounds - much more powerful than either Vickers' Class 'C' .5-inch (12.7 x 81mm) or the Browning .50-calibre gun (12.7 x 99mm). (Note: the RW Vickers Class 'F' was a .303 tested by the RAF. It was similar to the belt-fed Class 'E' but with an interchangeable feed block - for a belt or 97-round Lewis drum.)

[2] The .75-inch (19 mm) Vickers Class 'J' cannon was an larger-calibre development of the failed Class 'G' - a .661-inch heavy AA machine gun. (Note: the RW Vickers Class 'J' was rifle calibre aircraft machine gun - fixed or flexible - for export. There was an unrealized RW plan to enlarge the .661 AA gun to .75-inch calibre.)

[3] Here, Vickers-Armstrong was trying it on. Their Class 'C' had already been rejected by the RAF in favour of Browning guns.

[4] Although technically detailed to RAF Kalafrana, this 'det' was actually flying off the golf course grounds at Marsa.

Those Spectres are wonderful eye-candy.

For some reason, adding the Vokes filter for a desert version makes it even more believable.

Superb Spectres!
