Just the one gauge? not the compass and other things in the picture?
(I have some lights; a weird mix of a UK HID missing the bottom plate, an old D8 Xenon missing the top plate, an IkeLite pro V8 LED video light that lost the bottom plate. All the light heads work, but I don't use big lights anymore, so it is not worth it for me to buy the little parts to fix these just to sell them.
I could throw in two or three K inflators, and the lights and swap for the gauges, and the pony and the Zeagle BCD. Or something. Also have a Scubapro r190, or some iffy USD second stages, or an Oceanic button gauge, or a hemispherical swivel.
I have seem to have a bunch of spare stuff now that I think about it.
