The bolt on the side with a graduated plate under it is the adjuster. Distributor turns CCW when viewed from the front, moving bolt CY would advance, CCW would retard.
I've posted the secret instructions on establishing a starting point (spec is 4 degreees) but centerline is real close.
Investigate having brake backed all the way off, then back down just a little to maintain stability, and see what advance curve you have as marked on rear of shaft. The 11a 1941 curve is quicker than the common 68 and will help.
