Missed those. I've seen similar types of listings in the vintage Nikon auctions where sellers go "fishing" by putting super high prices on their items.
I've learned to keep an open mind on values. Some years back, a gentleman put up a rather ordinary looking Crosman 101 on Ebay with a starting price of $200. I took the time to write the seller that his pricing was out of line with reality.... ended up selling and for more than $200!?
And, note here that I saw the $400 price as being a record maker and the darn thing ends up over $1500!!!!!
I've long felt that vintage airgun values were below their true worth and that Ebay was the only way to establish some real-world market values. The Blue Book of Airguns, from the beginning, only reflected the guesstimates of a select few collectors (Which included me, so I understand exactly how it was all done.)
