Dug up some not fully attributed coins and among them was the following:

It is clearly a Caracalla from Hadrianopolis (Thrace) but it is not in Sear and the closest I could find is Vorbanov#3496 at Wildwinds. The obverse is identical apart from "AVT" instead of "AVP" but the reverse diverts a bit.
Had a look at the Moushmov listing as well but no help.
Does anyone have an idea of a proper attribution or a source where I could find one online?
Or do I have to leave it as Vorbanov#3496var until I get a chance to dig into BMC or other specialised catalogues again?
