No holes, which makes me wonder if it is a derivative of the 2a or 2b. And the "arm" is flat, with no bevel or marking where the wide angle scale would be. . .
Lens appears physically scratched and looks as though it WAS coated. . . Just wonder if it's possible to polish the scratches out with Cerium Oxide, but I need to wait till I get the film back and put a film through it first.
