Guess it depends on definition of “used”! The RAF used me 109s, FW 190s, captured, repainted and used them for training. Didn’t say they were stock aircraft.

Poland
During World War II, five Polish Air Force in Great Britain squadrons used Mustangs. The first Polish unit equipped (7 June 1942) with Mustang Mk Is was Flight B of No. 309 Polish Army-Cooperation Squadron, followed by Flight A in March 1943. Subsequently, 309 Squadron was renamed No. 309 Polish Fighter-Reconnaissance Squadron and became part of Fighter Command. On 13 March 1944, No. 316 Polish Fighter Squadron received their first Mustang Mk IIIs; rearming of the unit was completed by the end of April. By 26 March 1943, No. 306 Polish Fighter Squadron and No. 315 Polish Fighter Squadron received Mustangs Mk IIIs (the whole operation took 12 days). On 20 October 1944, Mustang Mk Is in No. 309 Squadron were replaced by Mk IIIs. On 11 December 1944, the unit was again renamed, as No. 309 Polish Fighter Squadron. In 1945, No. 303 Polish Fighter Squadron received 20 Mustangs Mk IV/Mk IVA replacements. Postwar, between 6 December 1946 and 6 January 1947, all five Polish squadrons equipped with Mustangs were disbanded. Poland returned approximately 80 Mustangs Mk IIIs and 20 Mustangs Mk IV/IVAs to the RAF, which transferred them to the US government.[13]

Honduras
Seven Mustangs were acquired from private sources to fight in the so-called “Football War.”

Japan Captured, repainted and flew:
P-51C Mustang?S/n 44-10816 “Evalina” flown by Lt. Strawbridge, captured in China, 1944

Perhaps something more like this one?

Are we talking “real” B-17 plans or model? Here is a link to a free download with 3-views and “sections”, in Russian, but it is a free download!

The Lysander at the Canadian Warplane Heritage Museum of Hamilton, Ontario, Canada, was a TT version, so they may have further info for your study

As this started out to be an “Aces” stories thread, the drift has leaned to aviators in general. Perhaps the reason Aces are reluctant to talk about their experiences is that the PR Pedestal they are placed upon is an uncomfortable place to be. Our aviators of all brances put their lives on the line, yet just a few became the “aces”.

I had an uncle who flew Hellcats in the South Pacific. He never saw a Jap plane in the air, but shot up a bunch on the ground. Landing on a pitching carrier is dangerous enough without people shooting at you. He showed me a pic of this Hellcat after his wingman nearly killed him. On the deck waiting to take off, his wingman jumped the brakes and that HUGE prop ate it’s way up his fuselage, stopping just a foot behind the cockpit. Cut it to nice little 6″ sections!

Aces are a romantic notion. An Air Force Public Relations persons dream, but for the bulk of the service, just doing their job and living through it …I say, give them all praise and thank them…Ace or not. They served. They put it on the line. They lost friends to enemy, to accidents, to the weather, and those that just dissapeared.

Still working my way aft trying to figure out rivet patterns on my large scale Memphis Belle profile, I am aft as far as the engine nacelles and life raft hatches….rivet by bloody rivet! Spare time is the problem…have to make a living and aviation illustrations sure doesn’t do it !

Here is that thread to the chaps that got the Whittle up and running. Quite an accomplishment!
