Number of exhaust duct ?

[Kurtl]

Looking forward to identify this unknown american aircraft. Just have seen a few small parts yet, but with number on it. One looks like an exhaust duct shows "104-42010 2405", "104-42010 3408", and two little stampings with "32und 21". Can anyone identify these numbers and post a drawing of that part?

Another parts shows "BOHNALITE" and the number "609818".

Thanks for any help.

104 series numbers come from North American Aviation and were used on the P-51 line. That's definitely a Merlin exhaust. My guess is you're looking at a P-51 wreck!

And is it possible to determine the type of the engine for example to find out which version of the P-51 it was? I think that someone it this forum has a part list of the Merlin Engine and could provide us with further details - thanks. Kurtl

Hard to say - let us know if you find more aircraft parts or any parts with stamps on them.

I have it on good authoruty that 104- numbers are used only in P-51B models apparently

Gentlemen, here are some new pictures of the same crashplace. One part, looks like a holding for something shows the number 102 421 (first picture). Does this help?

The sheet alu part shows some olive color. This could come from the engine cowl in front of the cockpit.

What you think about the valve on the last picture. It has a diameter about 5 cm. Could it help to determine the engine type exactly?

regards,
