First time I ever saw one would have been around 1975 in the window of the British Gas showroom in Edinburgh. Actually, there was a music shop - McLarens(?) - on the upper floor and they must have had an arrangement to display some stock in the street-level window.
The Ripper had a cherryburst finish and I can remember the body looked huge compared to, say, a Fender. It lasted two weeks in there until one night the window got done in and the bass stolen.
