Anyone have knowledge of Unertl scope values? I picked up a Unertl 1.5" 20X Target Scope 25.5" in length. Serial 53770 which shows it was made in 1965 by the "Yahoo Unertl Groups" blog info. It's all original including Unertl rings and in perfect working order but shows range wear on the objective sunshade and tube top rail where the recoil spring tension is set. I'm thinking about selling it and the gun it came on H&R M12 22LR which is a loose clone to the Remington 52 Target Rifle. So I don't know if I should seperate them or sell as one?:smiley_confused_vra
