Help ID caliper & fork

I think these maybe off an H2 and somehow made their way onto a KZ, or the forks are from a Z.
this is the mongrel 77A1 that I have btw.

anyone please chime in if you have any info that may help to ID these or what I can look for to help ID them ie casting marks, ect.

to add.

H2 caliper Z1 forks

My bobber (KZ400 based) is a collection of many manufacturer's parts and I have used this web site, www.cmsnl.com/ to have a look through the microfiche drawings and identify parts. It helps if you have a vague idea of the parts original source.

thank you gents

Agree, I had the same on the H1E, but the forks look the same for a Z1 if I'm not wrong???
