Is this a 78 gs1000 front brake caliper??

So I'm rebuilding my front brake caliper on my 78 GS1000 and I just need a dust seal for the piston and some o-rings. I keep searching for info on this caliper but every 78 GS1000 brake caliper is different from this one.

I picked this bike up a couple months ago so I'm not sure if it's the original caliper. The bike is a spoke wheel GS with a single front caliper.

Is this the original caliper? If not, anyone know what year it's from?

Round pads, it's 1979 or earlier.
I think it looks right for a 1000, but I don't have one here to compare.

Can you post a pic of the face side it would help
Hear is a pic of mine

The one you have looks like the same one that was on my 1979 GS1000L from the pics you posted

Looks like it is a 78' 750 caliper. Found it on bike bandit.

Thanks

Check the parts fiches to see if different 750 models used different sized pistons on those first few years. I don't remember off hand.
I know for certain that the round master cylinder reservoirs took different parts. (different diameters for some odd reason)
