Value of Polarex Unitron 132F 4" telescope

I am being offered a Polarex Unitron 132F motor driven refractor telescope with all the original accessories, in very good condition but I really have no idea what a fair price would be. Any suggestions would be most welcome.

I'm not aware of any sales of the 132F model (4" folded compact model), so can't say exactly. I would expect it to have about the same pricing as the 152 model (4" full length scope), which for "very good condition" is around $3000 to $3200.

The term "very good condition" if subject to some interpretation. I would say it means fully usable scope with no major dents or damage. Maybe a few minor scrapes in the paint would be allowed; maybe some oxidation or traces of rust that could be mostly cleaned-up. Coatings on the lens should be mostly intact with little damage.

The compact 132F model is extremely rare, but I am not sure that increases the price. Personally I prefer the full-sized model, and would not pay extra for the compact. But if you found the right collector who absolutely needed one to complete his / her collection, then I suppose the pricing could go much higher. Also if it is merely "very good condition" vs "mint" a collector might be less interested.

Here are some examples of the 152:

Mint, motor $3750 SOLD
