When I saw the title here I thought it might be about the gal that use to repair our Delta computer terminals at work!!
Also thinking of the Delta, years ago I was given a copy of a 1911 page from a Parker Bros. ledger on another subject, and it included an order from a firm in Morgan City, Louisiana, for two 12/38 P.T.P.G.!!
Wonder where they are now? In Gary's collection?
