Thanks everyone for the advice. I'll tear it down and get everything lubed. I may have mistakenly called it a service replacement due to the tag attached to it. I'll dig up the warranty card that came with it, looks to have been done in the 50's. Here are a few more pictures of the engine.

Question: It currently has the crab style distributor but came with an NOS or rebuilt "helmet" style, and a different timing cover. The engine is going in a '41 Convertible and I'd rather run the 41 style. Anything I need to know about swapping that?

It came with a couple reconditioned (NOS replacement) distributors (crab style) if someone needs one. And a bunch of caps...
