The Resilion rear mech was released in 1954 and made by Philips (according to "The Dancing Chain"). It attached to a bracket on the chainstay which was either brazed or bolted on (this is not supplied as part of the listing). The derailleur is for 1/8" chain and 3-speed block. This listing includes a suitable NOS 3-speed block made by TDC.
This mech/lever/cable and block are all brand new, NOS. The deep chrome is very shiny and everything is working well. The aluminium cover plate to the lever is made of very soft material and it may have a little dint to it as a result.
These are very unusual derailleurs from the early days of the 1950's and will make an interesting addition to any cycle of the period.
Note shipping costs, which include the fees that sellers get lumped, even though the costs are unavoidable. The costs are estimated and any overpayment will be refunded.
