I keep finding more parts as I clear out storage areas. Please contact me if you are interested in any of the items in the following list. The proceeds from the sale of these parts will be donated (and can be paid directly) to a local non-profit organization, this is not a commercial venture. Please make an offer for anything you are interested in. These parts are of no use to me now, so Im open to almost any offer. Offers for larger batches of parts will be given priority. Thanks in advance.
