This is a VINTAGE OEM NOS 1950-60's FORD LINCOLN MERCURY SWITCH PART# FDC-18272-A? NOS.
It has the Manufacturer's Name (RBM)  and MADE IN U.S.A. stamped on it.

I'm not sure of the Part# and don't know the  FORD  Make, Model or years this is for. Please ensure this is correct for your application before bidding. See photos for details. Not tested.

I bought boxes of NOS obsolete parts from a local FORD dealership in the early 1970's.

Check my other listings for other NOS parts. 
I will combine shipping for multiple items purchased and will send an invoice at the end of the auction.
