J50 Brakes

[High Level Kits]

I’m looking for pictures or a drawing of the early non-compensated, brakegear from J50s class - that's those with two pull rods, one at either side running behind the wheels as opposed to the single zigzagging central rod on the more complex compensated gear ?

This will probably be similar to a J52 so that might do as well.

Thanks,

Chris.
