Identifying brake calipers

So... recently I purchased a K100 for the leading link front end.

Plan is to put it on my K100 outfit.

So... pulled it apart a bit to see what it's like. All seems ok,
except...

The front wheel looks like a ZXR of some description.

The calipers however, I can't identify. They wouldn't fit onto a
ZXR750H1. And I'd like to overhaul them.

So pictures here:

They are four-piston pots. The pistons are all 27mm diameter.

There are no real identifying marks on the calipers; don't know who made
them, apart from "DOP" on the pad inspection cover the only other
markings are "E1" on the caliper and L and R on the appropriate caliper.

The brake pads are labeled "Genuine GS-32" but no manufacturer.

Any ideas? I'd really like to get a seal kit. Would 'generic' 27mm
seals work... Where would I get these?

 

They look like early Gixer 750 ones to me. I know they had DOP on the
top cover, but not sure if they also put that on other calipers of that
era. I know that some Suzuki rear calipers had the DOP on the cover
though.

Same caliper I think, just gold not black.

 

Excellent. Looks identical.

Thank you very much Lozzo.

I hate to admit it (after the BMW flame bait...) but I had expected that
you'd answer this one.

Right then... set of caliper rebuild rubbers and we're off.

 

That's ok, I have a good memory for this kind of old shite.
