I had one that fit my Hasselblad and Yashicamat; it was very secure.
I don't recall if there was a 6x7 adapter, but it wouldn't surprise me.

I found the Sunpak 4205 instruction manual online and there was quite a range of accessories, including what is described as a 6x6 bracket (No 9 here) which has a square-ish platform instead of the thinner bar that I have (No 10). There was an optional belt-carried 510v battery pack (No 1 & 2). It would be hard to find these accessories today. The trouble with a normal flash bracket on the 6x7 is that the main "tripod" screw socket is forward under the mirror box (where the centre of gravity is) rather than under the main body, so there is less area for the flash bar to grip. There was a special bracket to fit the Pentax AF400T to the 6x7 I believe.
There was also a Sunpak G4500DX (555 in America?) which looked very similar, had a slightly higher GN of 45, and had optional modules that fitted in the camera hotshoe and added a TTL mode if the camera supported it. I guess the 4500 was a later model. Those modules (especially Pentax ones) are rare on Ebay. I believe these two units shared many of those accessories. There was also a monster 622 with a GN of 60. The 4xxx series look designed by the same committee as did the Pentax AF400T. I read once that the Pentax flash units of the 1980s were in fact made for them by Sunpak - does anyone know if this is true?
I like hammerhead units, especially as there have been questions about the strength of DSLR pentaprism housings, but they seem to have gone out of fashion - do only Metz make them now? I got my 4205 from Ebay at the ridiculous price of £10, I felt like a thief : I don't think the seller knew the first thing about it as they packaged it as the complete "L" shape without taking it into its two parts!
