M_Boats: M17 rigging continued

Ok, last night I was able to compare the masts side by side and take measurements. I will be able to use a tabernacle with no problem. I'll return the hinged base. Oh while I'm on rigging, can someone confirm if this is an original bow plate from the mid 70's? Someone expressed concern that it wasn't, or was not in the right spot, or might pull the bolts through the deck. There isn't a backing plate, the bolts just go through the deck. I see no signs of modification in this area though. -Gerry
