Oh yeah, and if were' talking Mustang Copies, there are none I can think of in modern times, I'm literally COMBING Vintaxe for all their offset content possible....so far I've found these brands of guitar that had Mustang versions....
1976 Castilla CE-102 - This is sort of like a Fender Mustang crossed with a a Harmony H-802, it has the same pickups as an H-802, same trem as my Zenta tele as well as identical switching. Very cheesy looking, and has one of those doily looking pickguards found on some old student guitars from around the same time.
Fresher FMT - One of these turned up on E-bay in Germany last year (and subsequescently on ShortScale). This is Fresher's earlier Mustang which looks like it has 2 Telecaster neck pickups, a Jaguar Trem, a Univox Bridge, and a maple neck, often in blue, sometimes with black or white competition stripes.
Fresher Mercury - The later version of the Fresher Mustangs that looks almost identical to a Fender but apparently lacks the phase switching feature. Even more hard to find than the other.
Fernandez FMT-65 - A 1981-1982ish version of the Mustang marketed by Fernandez, looks a lot like Fender's "Mustang 84'" in that it's vintage white with a maple neck, tortishell pickguard, and black switches and pickup covers.
ESP Mustang Kits - ESP was selling "MG" guitar kits in the early 80's, which were dual humbucker routed bodies and 24" scale necks (apparently) and several different HH or SS pickguards to choose from to build your own Mustang (or possibly Duo-Sonic) with.
ESP Char Model 82' - Char is a Japanese musician who is well known for using Fender Mustangs. They built a sig-model type guitar around 1981-1982 for him that resembles a Mustang with the bottom just lightly cut out, a Strat trem, and a different headstock, but it's obviously a Mustang derived design.
Orion/Zenta/Hondo/place-other-oriental-name-here Mustang Copies - There were a bunch of cheesy Mustang copies sold under several names but are basically identical. They feature either plain cover or the same pickups as the Zenta Tele copy I have, the exact same vibrato (but with a different bridge), on off switches for each pickup in the usual Mustang position, and are 24.75" or 24" scale (can't tell from the picture). They look mostly like a cartoonish Mustang, but the dimensions and shape of things are way off actually.
I'll continue looking and see what I can dig up....I'm also collecting pics.
