Is anyone aware of the existence of a "Workshop Manual" that is a book of technical specifications for a 1927 6-66 Auburn, with the Lycoming SM engine (not a 6-66A with the Continental motor). The ACD museum has an owners manual for a 6-66A but it covers little technical data and has obviously nothing on the Lycoming motor.
Thanks for your assistance
