I've just picked up another of these, albeit in this case uncleaned. My impression is that there may be a good deal of detail extant beneath the encrustation. I'll start the conservation process off with the standard long distilled water soak, but will ask if anyone has suggestions for (properly) removing these deposits beyond that.
While there are multiple very similar types cataloged separately, I have this one as RIV VII 70 (Sear 16528), struck at Alexandria.
