I have one of these in excellent shape but it is missing the head mount screw in the crown. Ries does not have these available and suggested I send in the crown (3 7/8" dia.) for them to make one, which I think I'll do locally (unless the consensus is to let them do it).

If anyone has one of these models and has a pic or specs of the head mount screw to send me, I would appreciate it.
Then I can take to my machinist friend. If there are other options you know of, please inform.

Serial no. 4154 with the "Hollywood" stamp underneath crown.
Thanks!
