Yes, deep notched for a glass body for sure. Luckily the chip went down instead of up, so it will still sit on a screw properly. Does this lens have a sort of "pebbly" almost matte-like finish to the front? I can't tell from the pics but it looks like the pair I have with the almost clear look to the usual white areas. They were made for a glass body so didn't require the white frit. Mine are not "C" marked either and were likely produced by a different company than CAPCO. I bought my now pair as singles and it took me quite a while to find another to match this particular style lens. I know mine are not reproductions......
