Marty in Buffalo.

All those parts are off a KZ650, the CSR has a different fender, that fender is off a B, C, of F model.

 

Thanks!! I have other items on eBay now. 
I just don't know these items. Don't want to deal with them.
 

I think the DGM number is for Italian customs.  You can find it on various parts, notably the 76 KZ900 exhaust.

Possibly SR, definitely not CSR. The csr is almost completely different than the SR. I think the SR has painted fenders. 
The parts could be from some other 70s 650.

The KZ650-CSR actually has a 750-4 airbox embossed with KZ750E\H and the csr brake pedal is different.

I just checked a air box off a 1978 KZ650 B2 and it has the same numbers on the plastic.
The air box does not have the pollution hole at the top so it may be for a non emissions Canadian bike.
All the rest of those parts also look like they are off a drum brake B model KZ650.
