Wot rear brake caliper have I got?

[domiles1]

Does anyone have enough knowledge of rear brakes to answer this? I am rebuilding a rear caliper that I thought was from a 1979-ish 750 or 1000. I've been looking at the diagrams on bikebandit.com and, according to them, all GS rear calipers seem to have two bleed nipples (one on each caliper half). My caliper looks just like their diagrams except I have only one bleed nipple - where the second one is on their diag is where my banjo/fluid inlet is. Been searching through the diagrams and cannnot find any like mine. Or is is just cos Bikebandit.com is American and the calipers were different spec?
Cheers
Dom.

A pic might help the mystery

Several of the rear calipers only use one bleed port. And yes, a photo would help.
