I have a Mauser type G in 9.3x62, it has an original optic on it, from the 20s, I can not read the writing of who made it, but it reads x5 on the tube and 200 & 300 respectively on the dial on the top, I am not familiar with the process of dialing in the wind & elevation of this type of scope, I shot it today and it was about 6" low at 50yrds. Thank you.
