Dear All, I have seen a number of threads here where people have said that they have details and/or manuals on these. I am restoring one and could do with all of the documentation I can find. So, can anyone help. I have to carry out the following: 1) Refill the bubble chamber. 2) Service the integrator (it is complete and everything seems to move but it is coming up with wrong answers - I think this is stale lubrication and the like). 3) Ideally I would like to resilver and recalibrate the mirrors but this is a luxury. Any maintenance manuals (scans or photocopies which I will happily reimburse for) would be gratefully received. The device, apart from a few paint chips, is complete and in good condition. In its box with a couple of battery holders and the unit for connecting to an external DC supply. I could do with some spare bulbs as one has blown but apart from that everything seems ok and works.
