Happy to oblige.
In fact, I posted a few pics of my TWB-6 in the TunePorn thread way back in 2009. This 'ere post:

However, I'll park a couple or three here and just say that Japanese Tune's are a bit like hen's gold teeth, at least in the UK. Well worth snagging one, though, if the opportunity arises.
Japanese vintage Tune TWB-6 (c.1991). Purchased in 1997 from the Bass Centre, Wapping.
Also bought this Korean Tune SWV4-BB a few years back (through Basschat).
