I'm selling my *like new* sterling silver Foster Extension on Ebay for $275.00 (retails for $350.00). It is basically brand new as I've used it VERY little since purchasing it from the NFA Flute Convention in Kansas City! It fits both B and C foots.
It comes with the original fleece-lined pouch and the actual extension shows no wear at all. For pics, please visit my Ebay selling page at this address: http://www.ebay.com/itm/140796064872?ss ... 500wt_1413
