It's the Duncan Automatic Stop ! That phonetip plugs into a little hole
on the back of the reproducer; when the limit pin touches the loop, the
Duncan stops the phono for you.

Subject: [Phono-L] Diamond Disc 250 Mystery
Hello Phonolisters:
Today while I was out looking for records I came across an Edison Diamond
Disc player, model 250 that had several items that I have never seen
before. Attached to the bottom of the brass portion of the top of the
horn
just behind the locking ferrule is a small brass pipe that runs down below
the motorboard and contains an electrical wire that starts with a small
phonetip on the upper end and ends in a bare end below the motorboard.
The
wire is about 18" long. Also interesting is an electric switch below the
turntable that seems to be part of the stop mechanism. Other than that,
the machine seems to be an ordinary 250 with a spring motor. I took two
pictures of the features that I have described above and would be glad to
send them to anyone who asks and who provides me with an email address.
Best Regards,
Green Mountain Bill
