The dovetail dimensions of virtually ALL mausers are SUPPOSED to be the same. You can peen the base over the blade if need-be, to tighten-up the fit. As far as the tallest "pyramid" type blade, you'll want to get blades from a Czech VZ24. These will produce a 100yd. zero on a Turk at somewhere between the 400m and 600m setting of the rear elevator.
