I was at a flea market and came across a Weaver Scope in traditional Weaver box. It appeared to be a 3/4" or 7/8" tube .22 scope. However, the scope had no crosshairs in it, and no turrets on it. It's not like the turrets were ever there, no holes or other evidence of turrets. I seem to recall the model being a D9 or K9 scope. Any ideas what this was.?
