Possible P-38 crash site Belgium

I have stumbled on a crash site in the Ardennes and have pictures of various aircraft parts, which were strewn in a forrest. According to public records, the only aircraft which went down in the particular area was a P-38. I am looking for type confirmation (or rejection). One part is a broken off piece of light metal, stamped with the brand name "Bohnalite". I have seen a photo on the web with this same stamp on the bank of cylinders of an RR Merlin Spitfire engine. However, I understand that the P-38 was exclusively fitted with the Allison V-1710. I would be very grateful if anyone can tell me whether the Allison V-1710 also includes Bohnalite components (on the web very little is to be found about this manufacturer/supplier).

Why don't you post the photos of what you have found? It would be easier to identify.
