I know how you feel. I picked up a very tidy Crosman M1 off Mike Watkins on here. A rifle that Ive been after for a while and rare complete and in that condition (manuals etc. plus a spud gun). Great person to deal with and a pleasure to meet.
Also on the airgun connection theme - my hours of trawling around various charity shops throughout the country with the Mrs paid dividends when she found a boxed Accles and Shelvoke propelling pencil (dated pre WW1)
Its little bits like that that are the cherry on the collecting cake.
You never know whats around the corner.
