Piston and engine reference

Hello everyone !
My name is Wilfried MARTIN , Im french industrial disigner.
In September a have go to National championship air racing at RENO. In the show i have buy one Part for WW2 aircraft. This is a Piston. Probleme i dont say what is the engine ? In the piston i have juste 1 reference. 3_110297-J 55335. I think he's coming to one Wright R-XXXX Cyclone or one of it is copy. I know very little about old engines .Can you help me ?

Just for information , the piston measures 154 mm in diameter and approximately 114.7 mm in height

Thank you very much!!!

Welcome and bonjour, WMARTIN. I don't know but someone here can probably help you.

It looks to me as a Wright 3350 piston whch is 155 mm in diameter. You might want to contact this company as they are the specialist in Wright engines.
