Omega SuperCharger plug type

I have had this air compressor for many years and it just keeps chuga-lugging along……… that is IF I could find the electric cord!!!!!! I recently moved and the air compressor, cover, filler hose and manual all are here but the cord is lost. The cord has a weird ( to me) end that goes into the compressor. Does anyone know the “ TYPE” end it is? I’d like to source it locally but if that’s not possible, I’ll call an Omega dealer and hope that they can get one to me. I have a “ great white “ tank now that I’m using for refills BUT I bought a 5000 PSI Huben K1 that I‘d like to fill to the brim straight from the compressor.Any help is very appreciated.
