Nishijin B question

[tgreidy]

Hi all, I'm new to Pachitalk. I've had a '73 Nishijin B for about 15 years, and it seems to work fine. It was getting kind of grungy, so I thought I'd give it a cleaning. Once I got it apart, I found it had been apart before and a MacGuyver repair performed. It appears a part broke and was rigged with a twist-tie to get it working. I also found 2 balls in a place where I don't think they belong.

If someone could post a picture of the part in a non-broken state, I would appreciate it, and also verify I can just remove the 2 balls.

BTW, I also have a '71 Nishijin recycler that I just picked up and gave a good cleaning. I had to replace the bottom board of the frame as it was rotting from water damage.

Thanks for any help,

Tim
