Theo Koch Chair Brake

[Jeremy Simmons]

I have a 1920's Koch barber chair. When I purchased the chair it was in decent shape, but the seller handed me a brake that had come off of the chair. I've done enough research to know that it is an automatic brake that locks the swivel when the chair is raised to the highest position but I have not had any luck determining where the brake belongs on the chair to put back on. Does anyone know?
Thanks,
Jeremy
