Jardine oddball header ( KZ650 )

Maybe not so odd to some of you but I just picked up this Jardine header. Odd thing to me is it mounts on the left hand side of the bike. I have never seen this before. Got it off a 77 KZ650 C1. Should have grabbed the whole bike before it went to the crusher but just to far gone to justify dragging it home. Pipe was in very good shape though.       

Wow, what a waste, another lost B1. Thanks for the photos, and if you come across a nice pair of engine crash bars, I would be interested. Trying to find parts in NZ is very difficult due to the small population.
Rich.

Not to start anything but the pics in the OP post appear to be a C1 model and not a B1.

As to the header it appears to be in good shape for as old as it is. I was aware of the cross over system Jardine offered, and the turnout systems, but had not seen many left hand side ones from them. There were other left hand side systems offered back in the day.
