I recall only seeing one UK ebay auction of a Taito Balloon Bomber myself over past 5 to 6 years. I don't recall if it was pcb only or if it was entire cocktail table. I haven't been specifically searching for that myself so there may have been an ebay auction listing or two that I missed because I would be searching for other very specific items.
I don't recall ever seeing the manual being listed for an ebay auction nor the blue print schematics. Smit has paperwork (for Vortex) with one of the pages actually being previously a part of Balloon Bomber manual instead. The page provided a list of what the adjustable pots did for handling each audio sound effect for Balloon Bomber.
There should be a jpeg photo of that page over on MAME Testers web site in a Balloon Bomber entry.
