I have a couple of reproduction oiler fittings for the seat tube of your old Bianchi, Gloria, Benotto, etc. They were made by an Italian engineer and consist of 10 separate parts including a leather gasket. These are exact copies of the original oiler. The oil is inserted from the top of the seatpost and passes through a tube in the frame. For sale is the oiler only, as pictured, below. Price is 74.00 including shipping.
