At least, some I've not seen before that I can recall. Progressive identifier comes up blank too.
180 marks are teardrop shaped with a single dot in the middle (not the typical circle, or any of the other usual marks found there). Identifying marks look like a "W", with a "T" to the right of it. The W lookes molded into the lens, but the "T" and the add power are both dotted lines (like an old dot matrix printer) - guessing added later by laser. Custom something or other? Likely a short corridor as well.
Any guesses with that limited description?
