Deep in the attic the miners found a set of spare tubes for a BC-312-L and 314-D I no longer have, plus 3 pristine NOS toilet seats labeled PHONES SECOND AUDIO, MICRO, and KEY. All 3 have the felt pad inside the lid. $20.00 (medium top loading USPS Flat Rate Box postage of $15.50 plus a cold 807 for me 😋) Jim Falls K6FWT
