Help to Identify Douglas Air Intake Assy C-54?

[Bigmerle]

I'm hoping someone can help me identify what I believe to be an "intake trunk" assembly from a Douglas aircraft. I'm unable to post a picture as I'm not in possession of the assembly right now. What I can offer is what NAA would call an "Install" or assembly number. The number 5169508-403 is stamped on a metal tag that is riveted on one end of the unit. There is an hydraulic actuator in the assy about 8-10" long with cast aluminum head on each end. There is a part number cast into each one. 2067204 on one end and 2067238 on the other. These 2 part numbers may not show up in the parts book as they don't appear to be replaceable. From what I've seen in my search of some Douglas parts manuals I have access to these part numbers fit the patterns used on Douglas part numbers. I've looked in an SBD and a A-24 manual but haven't found a number match. Perhaps a C-54?
Thanks for any help you may be able to offer.

That p/n doesn't show up in the IPB's for the A-20, the A-26, DC-3, DC-6 or the C-54.

That parts tag should have an inspection stamp on it and that would confirm Douglas. Ask you source to look for stamps about 4-5mm high. If DAC it will be an elongated D with a number inside. Ignore all stamps that consist of the letters H and T in any format as those are Heat Treat stamps.

As you say the parts format fits Douglas but other companies also used that format.
