What is the function of this part

REAL coin-op collectors will know what this part does. Perhaps someone could enlighten me as to the requirements for becoming one of the few "REAL" coin-op collectors.

I'm by no means an expert, but I do recognize that part. It took me about 4hrs of staring and cycling and tinkering with my QT which had been sitting in my garage for years, to figure out the cause of the slow reels. Fixed it with a dab of weld and grinding back to original profile. It was very satisfying to get that machine humming again.

In my lowly opinion you score very high. I like the weld trick, but I don't know anything about welding. I was able to find a manufactured part and made the repair, still had to do a little grinding to make it function correctly. Hard to beat those little QTs. Thanks for the comment. Keep up the good work.
