Want to Buy WTB; Counterweight for Elwood 5x7 Enlarger

Hi, I'm looking for the metal counterweight that slides up and down behind the column of a 5x7 Elwood enlarger. I don't know the model, but it's one of the wooden ones with the rack and pinion elevation setup on the column. If you have a wrecked Elwood or a spare counterweight please PM me.

Thanks,

Mike
