M_Boats: Fitting for bottom of mast for Montgomery 12 and lots of questions.

I'm going to be getting a Montgomery 12 back on the water again and I've got lots and lots of questions. It's mostly there, but there look like some problems.    It seems there is a lot of sail for a light boat, so I'm guessing it was meant to go fast. How is the mast for the Montgomery 12 supposed to fit on the bottom of the boat?   was it originally supposed to have a tabernacle like the M15? Are the sidestays and forestay supposed to be 1/8 "?   Seems the hanks for the jib would prefer 3/32" Any pictures or descriptions would be great.
