Subject: [MLA-L] Help! What is this?
| A colleague of mine in the Baptist archives came to me with a 6-7"
| aluminum disc looking similar to a 45 RPM single. Instead of the 1.5"
| hole in the center, there are three small holes arranged in a
| triangular pattern. Can anyone shed some light on what this might be.
