So like a lot of "Galaga" machines advertised, this one too is not a Galaga.  It's got black laminate over one side with a nice Galaga side art stuck on, but I can peel away at it a bit to reveal... a white Galaxian cabinet with really faded and beat-up artwork!  The other side has been really sanded and has a bit of black spray paint, I can still make out the Galaxian artwork near one corner.
Serial number stamped inside is 18681.  I don't really like Galaxian as much compared to Galaga, but the artwork is admittedly way cooler, so I'll do a Galaxian restore instead. Researching art options now.
The cabinet appears to be "all there" except the CP, artwork, PCB and monitor, and back door.  So it's like a three-sided empty box.  With coin door and mechs, leg levelers, and grill covers over the vents on the back!  But hey there's a parts box with what seems to be a power supply, cracked Galaga marquee, leaf ball-top 4way joystick, maybe some leaf buttons, speaker grille, a couple quarters, a transformer screwed to a board, and maybe some other odds and ends.
I'll take pictures sometime soon and figure out what to do next.
