Anyone have an old Supertrapp Catalog?

I've got an old Supertrapp megaphone with 4MSM-60750 imprinted into the muffler hanger. I know it's for a Kawasaki 650 or 750/4 but not sure what model or year.

Any help appreciated.

Edit: I think 4MSM is a reference for a megaphone muffler and 60750 seems to reference the 750E, H, and KZ650H & CSR
Hope this is true because I've got a 750E and a NOS Supertrapp header.

I've got one from 1989 but it lists a 4MSH-60750SS or a 4MSL-60650SS for the KZ650B, C, D, SR and the E (years not listed)
The same 750 number along with the 4MSL-60752SS is listed for the 1983-85 GPZ750.both of these are Superlight models and the Super street is not avaliable for the 650........... Trouble is the KZ750 is not listed and the 4MSM part number is not either..... (on any models). Hopefully someone will have a older catalog or newer that lists it.

I'm pretty sure 4MSM = megaphone system. There is a GPz 750 muffler on ebay which confirms that.

And a similar 650 system...

I'm also pretty sure at this point that 60750 is for the early 750E/H. Think I'm good to go on this system. Question now is whether it's worth the cost to have it chrome plated or just go with painted?
