Some time ago I purchased a box which at the time I thought would be useful for my husband's woodwork tools. It contained an incomplete telescope and I would like advice whether it will be possible to obtain parts to restore it, where I could purchase them and if it would be worthwhile to do so. The maker's label states 'Prinz Optics, Made In Japan, Astronomical Telescope Model 660 DE=76.2mm F=1250mm'. There is a draw tube but the rack has been removed leaving just one small screw. There are no eye pieces or lenses apart from the main objective. The spotting scope has no draw tube or lenses. I purchased a mounting unit from a general market stall into which the telescope tube fits exactly. I will be very grateful if someone could give me some advice please especially with regard to obtaining the correct lenses. There are compartments in the box itself for four eye piece lenses. Thankyou for looking.
