The 8121 is a small marine radio, with internal tuner. The antenna connector stud and ground stud are on the back panel.

It comes in boatie black with white decals. Internally it is very similar to the 6924 Mk 2. This illustrates the remarkable

longevity of the core design - 1969 to the mid-80's, and many of these radios are still in use today.
