Sumiko Premier MMT Tonearm (classic 1980s/1990s arm)

Description

Sumiko Premier MMT
is an S-shaped tonearm manufactured for Sumiko by Jelco in Japan. It's very similar to the Jelco SA-370H tonearm. This was one of the classic tonearms of the 1980s and 1990s, and was standard on a lot of high-end turntables.
Includes the original Sumiko headshell and a spare Technics headshell (see pics).
This arm has a standard 5-pin DIN connector for the tonearm cable (cable not included).

Minor Issues:
The clip that locks
the tonearm to the tonearm rest
is broken (see picture). This is only used when you're
moving the turntable or
changing cartridges, so it doesn't affect normal operation. You'll just have to secure the tonearm some other way when needed (e.g. twist tie or rubber band).
The white cartridge cable on the Sumiko headshell looks like a replacement.
The Sumiko headshell is missing the finger lift. It uses a standard removable lift, attached with the cartridge screws. The lack of a lift never bothered me, but replacements can be found for cheap on eBay and Amazon.
