Welcome - be wary of overusing the value section.
Do research first (checking e-bay current and archives, and auction sites) before asking here. Also if you get a value here of something you are going to sell, either sell it on this site, or post a notice on the oldgas online auction forum, when you have listed it for sale. This being done as a courtesy to members who gave you values.
If you are listing it on ebay, just put down the item number instead of a link so folks can cut and paste into the ebay search at the bottom of each forum. Oldgas gets a commission from each sale done through the oldgas search.
