The ODV-023 design had a long run in production. It was bold, with a high relief and towards the later years showed devices creeping up to the rim. The design was in use from 1960 - 1968. Then the short lived ODV-024 was introduced in 1969.
Is the reverse normal or does it show signs of a false or double rim as well? Thanks, Doug.
