I have this 20X54 unertl spotting scope that I haven't used for years. It is still bright and clear, but the finish is marred where the home made mounting system was clamped on. There was foam under the clamp, and the foam had bonded to the finish. In any case, I could not get an idea of the value of this, but I would trade it for a really nice rifle scope with an adjustable objective.
