    Re: Bubble sextant parts and calibration

    Appears coiled to me.  View larger photo with zoom.  The central section is much thicker than the leads on the outside, leading to the coiled conclusion.

    I found a bulb and considered it for a MK IX but Bill Morris (I think) said he thought it would be too dim. I later got the installed bulbs working and never went any further.
    There is a photo of the bulb and there may be a coiled filament wire. I can't tell for sure.
