Is there anyone there? I do hope this isn't moribund... I found it a useful forum a while back...

I still check things out here, but haven't had much time for my own projects.

I'm sure things will pick back up!

I'm busy with NUS Fleet on NAVALISM.

http://www.navalism.org/

I have no very much time to built at 1/700, HMS Indefatigable... & absolute no time to scratch an other NeverWere.

I hope to scratch the Alsace project this year.

Contrary to the tag, I think this is actually for an A-20, not a TBD

It is in nice shape.

Curiously, it is configured for torpedo running at 40.5 knots (non-adjustable), and I cannot figure out which torpedo this would be. It may be intended for one running slightly slower, with fudge applied to counter the initial speed from launch till water impact and deceleration of 150 knots or so.

The standard USN aerial torpedo, the Mark 13 had a speed of 33.5 knots.

Some A-20s were equipped to carry torpedoes but I don't think that any USAAF ones ever dropped one operationally. The DB-7C model ordered by the Dutch in October 194 could be equipped to carry one. Some A-20Cs (originally ordered for the RAF as Boston IIIAs) were taken over by the USAAF and fitted to carry a torpedo.

Yes, I am puzzled by the torpedo speed.

It could be that 40.5 is the speed chosen for the sight for a torpedo that runs more slowly, as 40.5 is the effective speed for the slow torpedo when dropped from a given prescribed altitude at a given prescribed range from the target. That is, 40.5 might be the average overall speed of travel of that torpedo as it runs at the speed of the aircraft as it drops, and as it decelerates to its sustainable running speed in the water.

It is more than possible that different torpedo arms could be swapped in and out, but such was clearly to be done on the ground and not in flight.
