So far, this ad featuring Larry Coryell is the only one I’ve run across. Japanese version.
Here’s a pic of Acoustic employee Harvey Gerst playing one of 3 left-handed Black Widows made. The short headstock and the fact that he references it in this interview as having 24 frets, marks it as a Japanese version.
The following 2 pics are from a packet of promo stuff I bought on eBay several years ago. These are 8×10 glossy photos of 2 different guitars. The first is a left-handed Black Widow, apparently of Bartell manufacture (22 fret neck with a long headstock). The 2nd pic is the more common right-handed Matsumoku (Japan) version (24 frets).
