WTB: Old-school Pentax (K-mount) Extension Tubes

[Darren Addy]

Anybody have an old set of Pentax (K-mount) extension tubes gathering dust in a camera bag in the back of your closet? The brand is not terribly important (doesn't have to be Pentax... could be Vivitar, etc... just needs to fit a PK mount). I realize I can buy these super-cheap on ebay, but I'd prefer to buy this particular item elsewhere.

Please PM me, if you have one. Thanks!
