Question about two numbers on a data plate

patelie · **Posted:** Sun Oct 09, 2011 3:56 am

Hello

I have, on a data plate, two numbers for which I need some help. The plate belongs to a component of a C-47

- First one is 3141551-1 and is a part number

Is there someone who have a parts catalogue and who can check in the Exhaust Manifold Sytem parts to see if he find this number (I cann't find it in my parts catalogue)

- second one is W535 AC32725. It's the USAAF contract. Is there a possibility to know the range of A/C serials which were built under this contract?

Thanks in advance for your help.

Hum
I made a quick search and I found on two places that the range for contract AC32725 was 43-15033 to 43-16312
You can confirm?
Thanks

It seems that the range for the contract is different. I have a data plate with contract AC32725 and serial 42-101008

The aircraft identification card for 42-100803 show also a contract number AC-32725

But which is the begining for this contract?
s/n 18899 (42-100436) to s/n 20598 (43-16132) were built at Long Beach with following constructor numbers.

s/n 18898 (43-22751) was a A-26C-25-DT

any idea? or do you know a place to ask about the contract numbers?

Thanks for your answer sidsiko..

Another question :
A C-47A which was built at Oklahoma City was necessary with another contract number?
I am also searching the contract number for 42-92462 (contract AC-28405 ?)

Yes, some C-47A's that were built at Oklahoma City were
42-92024/93158 under contract AC 28405.
42-108794/108993 under same contract.
43-47963/48262 under contract AC 40652.

The contract number for 42-92462 was AC 28405 approved 19th of September, 1942.
