My local photo store can not get an Ilford footswitch new or used.
I just missed out on a footswich on Ebay.
If anyone wants to part with this part I am interested in buying it from you.
Otherwise I need to figure out the "pinout" on the four prong foot switch connector plug to the Ilford 500 Multigrade head and a source for the connector.
I decided that trial and error might damage the head so if anyone can help I would be very grateful.
