Re: Ebay kollsman periscope sextants

If thinking of buying a Kollsman Periscopic Sextant you need to know that there are bubble models and pendulous reference ones. The latter are generally considered easier to use and are recognisable by a device resembling a circular tobacco tin or enlarged ice hockey puck on the bottom. Kollsman Periscopic Sextants also come with 24V lighting for most users and 3V lighting for the RAF and Bundeswehr. 24V lighting will need more thought over power supplies. If you wish to make full use of any periscopic sextant, Kollsman or Smiths, Kelvin-Hughes, you really need a mounting for it. Unfortunately these are a lot harder to find on eBay than the sextants, because they stop with the aircraft although they do come up occasionally. DaveP
