39 Graham; CORRECT engine color???

[Dennis in CT]

I am told that the 39 engines were gray.....can someone tell me what shade of gray is correct? Is it a dark gray like a Buick, or is it a lighter shade of gray? The Buick gray is almost black. I was thinking of using Bill Hirsch's "MED Gray". Any thoughts???

PS> I am also told the bell housing is gray, same as the engine, and the tranny is red. What color red? Dark?

Would appreciate some feedback.

Thanks
