Thanks for the input. I found a "Book of Instruction Lincoln V12 - 136" -- first edition, printed January 1933. The people at the club library scanned it for me last Friday. As you say, it is a very good book. Finding it made my day!!
I do understand that there was not a specific shop manual for the car but on your encouragement I will keep looking for the service manuals.
My car is the one recently sold by Dragone (pictured in the latest "Fork & Blade"). I will post pictures soon.
