I would guess a CAT SWB would have been a rare, specialized piece of racing exotica back when it was available new in the 1980's. Back then you had to find out about RC racing (a niche hobby) by buying a magazine, going to a modelshop or a club. It wasn't like today where you browse the web one evening see something that takes your fancy, press a few buttons, Hey Presto! new kit turns up on your doorstep Monday...... but by then you've decided you want to try kite boarding instead and hide it away in the shed
my max. bid $600 still unsuccessful ......................
