[patelie]

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.
