The plate moves forward and is able to be polished to clean it up. I took the locks off and had hoped to be able to get at the adjustment. It will need to be taken apart more to get at the adjustment. I would worry about the gap between the plate and standing breach as from the patent all that would then support the plate is a 1/4" screw. Not very good in my opinion.
Will give a few more details later. If any are interested.
Cheers,
Laurie
