I am recommissioning a CVA 79 Milling milling machine and noticed some previous posts a few years ago on here about these machines. Having made a new spindle pulley I am looking for a picture or details of the spindle lock that I believe attaches to the bracket on the top left. Unfortunately most pictures on the internet don't have it or are from below, presumably it clamps around the pulley like a disc brake calliper. I would be very grateful if someone who has a similar machine could share a picture of it or describe it so I can reproduce one please. Thanks Rob
