I have had good luck at gun shows. Some are cloudy and need cleaning. Some have broken or missing cross hairs. Are you able to do repairs? Most vintage or classic scopes are not nitrogen filled so that makes it easier. Fine cross hair wire can be found on ebay. The last show I scored a Weaver B6 and a G2.5 for $10 total. I am trying to get out of Weaver scopes but the package came with a rubber eye piece to fit one of my Mossberg scopes. I see BC is your location and there are some good shows such as Chilliwack March 21/22 and Kamloops a week or so ;later.
