I have an old Air Arms SE90, I bought it about 1990 from Blackpool Air Rifles I think, but it has had very little use, perhaps 50 shots through it in the first few months. I only collect pistols these days, and I may sell it at some point, or trade it in with a dealer if there is a pistol I fancy.

Condition wise, it is mint, it looks like the day it came out of the factory, it probably needs a service as it has not been used for years, but the action feels very smooth.

Can anyone give me an idea of what it might be worth?

Cheers.
