Picked up a used one of these a while ago. Blue anodised and to be honest, installing it for
looks as much as anything else. Question: do I just set it to the middle of the scale, set things up as normal and let
whoever tunes it (eventually) guddle about with it?

Yup if you are going to take it to someone who knows what they are doing, just do a like for like with the standard pulley. TDC on the pulley in line with the dot stamped on the head - wont do any damage that way
