no 19 mk3

[jason meade]

Guys I picked up a 19 set mk3 that seems like to be in real good shape minus someone cut out the three switches, i/c, b, a, with lots of wire to fix, i picked up three switches with the intent to fix it however the switches are the old cloth covered wires and the 19 set is more modern with red, black and orange, must have been rebuilt later i would guess.
I am looking for a diagram so it can be rewired is there anything out there that would show these three switches?
The three switches have 10 wires coming off it however the 19 set only has 8, or would this just be a lost cause?
