Greetings everyone, I was hoping someone could help me get a hold of a service manual for the Topcon Super D. I've been offered one at a fair price but it has a jammed advance and mirror stuck in the up position. I can't be there with the seller to test it out but I'm hoping that if I had the manual I could see if it's listed as a fixable problem. If anyone has a service manual or any advice to share on this problem I'd be most appreciative. Thanks so much and best regards
