A9 Cruiser Self Propelled AA vehicle
« on: September 11, 2021, 03:40:14 PM »
As a back story, the A9 Cruiser tank, the first of the line in that role was effectively retired from front line duty in the Western Desert in 1941. These tanks were gathered up in a Cairo base compound. The A9 as a tank, was outclassed and obsolete, but the chassis and running gear were in sound condition and it was also quite a fast tank, topping out at 25mph. Vickers in the UK was developing Valentine using, basically the same running gear.
 When the Panzerarmee Afrika was sending the British forces backward, the role that their air power was having was not lost on some forward thinking Officers so a couple of REME engineering officers thought about a mobile, armoured Anti Aircraft platform, using the well tried and tested 40mm Bofors anti-aircraft gun. A low number of the best A9 chassis were modified with a rudimentary, lightly armoured turret mount and the Bofors wedged in. It was ridiculously cramped and difficult to operate, but it did work. These modified vehicles were sent forward to front line, where they performed adequately, always hampered by the cramped conditions, but only for a very short time as the RAF Desert Airforce got up to numbers and soon had air superiority. As these tanks broke down or became again redundant, they were sent back to the base compound, where eventually they were broken up. Very few photographs were taken of these and remarkably little documentation. Imagine the surprise in 1944 when the REME officers, then back in the UK saw the "new development 40mm Bofors AA tank" based on the Crusader Chassis

This all started with Apophenia's Profile work on the Christie Cruisers.

I had a Cromwell Models/Under the Armour 1/35 Resin A9 Cruiser, well predating all the new injection releases (of course) However the kit was pretty below average, several poorly cast parts, not the correct number of each running gear, resin that stubbornly refused to glue... it goes on. It ultimately got tossed in a box at the back of the cupboard in disgust.  The profile work got me inspired.

The main event of course was the Bofors. No way I was springing for a new Bofors for this. I do already have a built Bronco 1/35 Bofors. The kit has lots of unused parts from the other Bofors in their range and I was able to gather enough as a basis to start.
I got out the built Bofors as a guide to replicate in a rough enough fashion


Test fit on the chassis after that got a bit of rebuild work.. the tracks are bloody horrible


So after a full arvo session this is where we are at the moment

Oh, this has all kinds of awesomeness! Excellent bit of recycling - both in your basckstory concept and RW modelling  :D

Loving the scratchwork on the Bofors and its turret. And those blanked-off machine turret holes are perfect.

Watching with great interest  :smiley: :smiley:

We really need an annual "Best Post EVER" award...

I love Flak tanks for some reason, though I don't have much to show off at the moment. This is pretty neat!

I can relate to the track work issues. I am currently working on completing the 'Lobsterrod', a preposterous vehicle of villainous super science,
and have been using a set of tracks & suspension for a Sherman HVVS...the links are supposed to snap together (I don't recall the manufacturer-got them cheap from the consignment shelf) and...they don't.

Almost time to call it on the build phase. Nothing is going to make the base A9 Cruiser kit running gear any better

Fleshed out more of the fighting compartment and mods to the tank
Overall look. Finally found a use for the ROTA Trailer I bought many, many years ago, much before the AFV club offering


Fighting Compartment. Ammo Racks on the wall


Replace the MG Turrets with hatches. I figure that other than being quite useless in this role, it would open space for more interior ammo storage


The Bofors mods to sort of make it look like a Bofors. For what it is worth.. the Italeri Bofors ain't that great either and the etch sights much better than that offering.


Painting next. Another mojo hurdle to clear
Thanks for the encouragement so far

You really hate the crews on these things, don't you, BT! ;D

Not only crap tracks but a bloody ROTO trailer, to boot! :o

This is looking great! Your work on the Bofors gun itself is a major improvement  :smiley:

Overall, your Cruiser SP just looks more workable that the RW Crusader Bofors type.

Good call on turning the MG turret spaces into ammunition lockers. Maybe not all that accessible in action but protected from splinters, etc., unlike ready rounds.

Looking forward to the paintwork  :smiley:

Seems like a natural match to me. The Crusader and Valentines towed Rota-trailers. So, why not an A9 SP?

The RW Rota-trailer was sized for 2-pounder rounds - so we know that 40 mm Bofors clips would fit. Carrying fuel around in over-sized wheels seems a little funky to us ... but at least both petrol and limbered ammunition are well away from the SP crew.

So, ... what am I missing?  ???

Good link Womby, very interesting content, aside from the ROTO trailer bit.

This build is at the "that'll do pig" time
Bit of fun and finally found a use for a long term resident of the Shelf O Doom

A few shots to finish out.



Aside from the tracks, under paint the actual hull is quite nice and I am sure with due care and attention the kit would have turned out ok.
Ready Ammo is a mix of Bronco and AFV club versions, the AFV club stuff has excellent fidelity. The ammo box, also from AFV Club Bofors Ammo Set.
Spare Barrel box is from the Bronco Bofors Kit
Thanks for looking :D

That came out great! Excellent weathering and all the fine details - like the headphones - really add to the visual interest.

Excellent job, BT! 8)

Even with the Evil Roto Trailer encumbrance. ;)

Colours & weathering are top-notch! :smiley:


Don't know if you watched them all (there are about 12 YT videos, all up) but it's an excellent presentation from some exceptionally knowledgeable people.

That's for sure! I love the sun-faded and worn paintwork on the hull in contrast to the almost pristine finish on the new turret  :smiley:

The hinged platforms at the rear of the turret were obvious before. But, with the figures in place, those slatted sections really make sense as vital extensions of the 'workspace'. Nice!

Looks great!  :smiley:

Plus any opportunity to incorporate a Rota-Trailer into the project is a win!
