I have a Unertl scope: 24 3/4? long, 3/4? tube, 1 1/2? objective. It?s mounted on a H&R Model 12 rifle. Scope s/n 35789, #14 stamped on tube (assume 14 power). When was it made? Are there any manuals available? Did Unertl have a ?name? for this style scope? I would post a pic but haven?t figured that out yet.
