I just bought a brand new one for $10 from my local electronics scrap store, I could disassemble and post photos by tonight if that would help:
My model is 840358-01 Wyse RJ11 connector, it's a beautiful keyboard, really solid, all double shot and Cherry MX Blacks.
If anyone in the Toronto area wants one I think there were a couple more buries behind some boxes, for those interested PM me and I'll give directions.
