I found an old scope in with my dad's old stuff, and he has no idea where he got it from. It says "Ruko 3-9x40 Waterproof wide angle" on it. The lens closest to the eye swivels, and the power selector is right in front of it, which also (obviously) turns. The far end of the scope is threaded.
Any idea what it may be? Thanks in advance.
