"Japanese replica "Tower" pistol in approximately .69 caliber." Exactly what it is. There must be millions of them out there (well not quite that many) and most don't work. If anyone is handy they can be gotten into shooting condition and can be fun. Not much value, the highest retail price I remember was $40 and they were on the market for years. There seems to be enough variation in them to make me believe there may have been more than one manufacturer or there were changes over the years. I also seem to recall some of them being made in Korea.
