Peter--Just checked my lens. Gave it the fingernail test plus a magnifier inspection. Both focusing scales are deeply engraved including the number 50. Maybe you noticed that in my earlier post I was careful to say "on my lens". I am well aware that when I have two "identical" items they are seldom exactly the same. For example, I have thirteen Kodak Signet 35's and none of them are alike. I also know there are other possible variations out there that I do not have. Just for the record, I have a swivel foot meter with silk screened dial.
Are we having fun yet?
