I just received a BKL 260 D4 mount for my 52. There are no instructions as to the proper orientation. The mount has a (4) imprinted on one end. If I put the (4) to the front and the screw heads on the lever side it appears to be correct. Can anyone confirm this? Thanks for your help.

Yes, that is correct. Usually the marks go in the front, screws to the right.

That's correct.
