A place where restoration project-type threads can go to avoid falling off the main page in the WIX hangar. Feel free to start threads on Restoration projects and/or warbird maintenance here. Named in memoriam for Gary Austin, a good friend of the site and known as RetroAviation here. He will be sorely missed.

Researching a 1944 Mustang crash in Germany (wingfailure) the translated copy of the German Final Report of Enemy AF Equipment and Enemy Air Crews states:
Metal propeller: Blades 4; Type Hamilton Standard, DRG A 6523 A-24.
As the Germans found 4 .50 cal machineguns I wonder if this prop belonged to a B/C ?
The serial # for this particular Mustang however refers to a P-51D-5-NA.....(44-13735).

According to the aircraft type certificaste data sheet, these blades can be used on P-51B, C & D:
J6523A-24
J6487A-24
K6523A-24
J6487A-24
6547A-6
The J & K numbers refer to the blade shank fairing design. I suspect one may be a cuffed blade and the other is not. The A may have been an earlier (now obsolete) blade shank design. The -24 refers (indirectly) to the prop diameter which is correct for a Merlin Mustang.
