Musicmaster SD-12 Transcription Tonearm Info?


I have a Musicmaster Model SD-12 Transcription Tonearm. I cannot find any information about this tonearm on the web. Maybe someone knows something about it, I will be thankful for the information.
Here is a link to some photos I took:

Hi Billleebens, thanks for the information.
Hamlin Special was a company in Seattle, that sold audio equipment in the late 50's and early 60's. This turntable is exactly like the Suzuki Denki Musicmaster Point One Five, except mine is 4 Speed, 16, 33, 45, 78 RPM.
Hello Buconero117, thank you for the information. Can you please give me a link of the Gray tonearm you had?
Romyald, are you still active. I would very much like to discuss the Hamlin's MusicMaster TT.
