Identify these Calipers?

Picked these up off a mate, he thinks they might be late ST184/single-piston ST185 calipers. On them they have PBR, E2798 and ND39 stamped on them.

Any idea's?

Spoke too soon - I put $20 on them being AE82 calipers

PBR stamp means they would be a Aussie built car (Corolla) surely

They are identical to the front calipers I personally pulled off a 1988 4AC equipped Australian delivered AE82 Seca.

I have it here in front of me as I type, as they are waiting to go to the tip on Saturday.

Pulled them out of a pile of 12 or so, they were the biggest of the 'smaller' ones and bolted onto Celica hubs so it made sense it was them - I was incorrect! The correct ones were the 'other' bigger ones. We now also know they have the same bolt spacing as Celica/MR2 calipers so anybody who is looking to upgrade their AE82 brakes, that's how I'd do it.

Thanks guys.

Ok so, anybody with ST184 calipers - can you tell me what numbers are on the top of them? I've just taken them in to be machined and realised they aren't a matching pair (same piston, same shape, all bolts on, same pad etc - however one of the sets of brackets positions the caliper roughly 5mm out from where the other one sits).
