Beautiful.  Just had an odd thought (yes, I know, they are dangerous); how about a tandem-seat version similar to a tricycle-geared Beaufighter?

Does anyone know if you can get a 1/48 conversion set to do the Soviet torpedo carrying A-20?

Carrier based attack and torpedo bomber?  Perhaps more powerful engines in larger nacelles.

You would need more powerful engines to cope with the increased weight of arresting gear and wing-folding gear as well as the general structural beef-up for carrier operations.  It would be interesting to see such in USN three-tone blue camouflage.

Yes exactly, Double Wasp with the wing pivot just outboard of the nacelles.  Torpedo, forward firing 20mm, maybe even in a dorsal turret and a nose mounted radar.

As a subtle whiff, what about A-20s instead of B-25s in the 18 April 1942 Doolittle Raid?

Never crossed my mind  ;)

Suitably modified they may actually have been able to return to the carrier after the raid.

Finding images of A-20 Havoc or Boston fitted with under-wing stores pylons appears to be quite the challenge.  So, does anyone have a decent image showing such things or a drawing perhaps?  Late model A-20 and Boston/Havocs were built with mounting points for two pylons under each wing.  So far, all I have seen are images of late model A-20 Havocs armed with either smoke tanks (USAF Museum images) or the triple tube 4.5"/115mm rockets on a very flimsy looking mount.  I was hoping for something that shows what the bomb capable pylons looked like.  I suppose for a WHIF it really should not matter and should then focus on another Douglas product such as the SBD Dauntless or the AD/A-1 Skyraider for these pylons.  But it would be nice to at least know what the real item actually looked like.

Lousy images, but here's a couple of shots showing Boston and Havoc wing racks carrying bombs:

Thanks.  The rack shown in the first link is the type I am looking for and as usual, it is a crappy image.  The second image shows the type of rack more often seen and it looks like something cobbled together in the shop.  USAF Museum A-20G on display has that same type of rack.  Unfortunately, not the one I am looking for. 

One of my references has an image of an A-20 in the PTO with zero-length launcher stubs and loaded up with 5.0"/127mm HVARs, a most unanticipated discovery and quite a source for further what-iffery. 

***Some kind soul at HyperScale shared a couple of images of the bomb rack in question.  Plus additional images of the bomb rack I was not interested in.  From the image it appears that there is no real pylon, just a bomb rack attached to the underside of the wing, very much like what was seen on the SBD Dauntless/A-24 Banshee

Would they be similar to the zero length stubs used on the Grumman Tracker Jeff ?. There's some photos of that in the Signal Squadron Tracker in Action book.

No idea Robert.  What is seen in the image of the A-20 armed with rockets is a set of stubs extending down from the wing to carry the rocket. 

Also, I just shared that image with you via eMail.

Came across some neat galleries (linked to on Britmodeller) while looking for info on the Special Hobby Boston Mk.III I'm currently building.

LINK #1 - A-20 low level bombing training (in the US, I think)

LINK #2 - A-20 "Mosquito killers" - DDT-spraying in Italy

LINK #3 - A-20s of the 410th BG May 44 to May 45

These could also be used as inspiration for a post war fire bomber conversion.
