I will stretch the topic a bit, but seeing as I haven't built a Model airplane in at least 40 years, I am going to consider my 67 Pontiac Firebird a 1/1 scale model at this point. The engine and transmission are out (the engine went bad 2 years ago after 106,000 miles) And is almost ready to go back in the car. So I decided to clean up the Saginaw 4-speed transmission cast iron case and very heavy. So here it is dirty and on the bench.

And after removing the shifter and mounts and vibration damper, 3 hours of cleaning, and a fresh coat of Cast iron paint from a rattle can.

Interesting that I found a Paint stamp still on the transmission after 57 years and 106K Miles. Looks like a Yellow FH so far not found in any of the info I can find online. But that is not surprising as most of the info is for V8 powered cars, and mine is a lowly SOHC-6 Sprint. Not much info published on them, I will have to dig out my manuals to see what they say.
