Hello all I haven't posted in a long time life keeps getting in the way. I am slowly getting back to restoring my 1938 ot hw sponsed canoe. I am setting it up to sail.I picked up a nice hand camed mast seat. The brass mast ring in the seat is held in by bronze oval head slotted screws that are missing.I have the mast thwart that came with the old town sail rig.I have those screws they are 3/4 inches long but a larger diameter hole in the mast ring for the thwart than the seat ring.What is the proper screws that old town used to hold the mast ring in the seat.The seat is a 1921 aa grade seat Also where can they be found I don't need 100 screws just 4 to make it look Orginal. Thanks Jon K.
