I was chatting today to someone who said they have a HW80 'somewhere' up stairs, that they have not used for years. all I know is that it is .177, and circa early-mid 1980's (if he remembers right)......assuming little use, good condition and properly stored as he claims, what would be a ballpark figure one would expect to have to pay please (he is not a shooter so has no idea of value, and this make / model is not my normal type of thing)......many thanks in advance!
