If someone went to the trouble of making a copy this well don't you think there would be others out there to make his effort worth while? None have been reported that I know of. I have four Oberkochen Zeiss from that exact same era and none say West . They are 8x30, 8x50, 10x50 and 15x60. Your 8x30 is exactly like mine. You have a Zeiss no doubt.
