arsclist Fw: [MLA-L] Help! What is this?

["Paul T. Jackson" <trescott@xxxxxxxxxxxxx>]

Perhaps someone from ARSC could enlighten this person from MLA?
This is probably a transcription disc, but I don't recall any such machine in my past experience.

| 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.
