Having got a 1/72 Ilya Muromets bomber, was pondering whiffs. Could modify to be a late 1920s tech heavy bomber.
1/48 DH-10 should also modify to 1/72 late 1920s heavy bomber.
Don't recall there being any heavy bombers at that time. Thinking heavy bomber comtempory of Keystone B-3 thereabouts.
P&W 1340 or 1690 engines - something like that.
