    Re: Kollsman periscopic sextant mount

    The Kolsmann bulbs are 28V, but fairly readily obtainable. You may still need the bubble light during daylight to get a good balance between the target and the bubble. You could use any handy 24v dc or ac power supply to run it. The 9v batteries wont last any time.

    Question: Do you know if an RAF Mk2b will fit a Mk1 sextant mount?
