That is just the outboard top/bottom of an MX, if you could find a used MX in decent shape they are usually cheap, you could make two of these (as if they were on the back corners of a fire engine).
Just my $.02, I have never seen JUST one of these minis for sale.
if feeling adventerous.........i have almost all the parts needed to make your own.
i have these:
2 lower domes (polishing them would make look decent)
metal rotator decks
abundance of lower lights (no sweeps unfortunately)
1 freeform rotator
possibly have a set of cascade mirrors (someone was interested in them, but no word back), also getting a few other MX parts, but not sure what all is included.
Thanks for finding that, shues...forgot all about that thread.
They're not hard to make...had to cut 2 lower domes to make 1, cut a few center decks to size, cut the fiber-board dividers to size & order new lens gasket strips from Code 3. The upper domes are the same for the Excalibur 22.5" beacon.
