This is in for a full overhaul.
The machine has been fully torn down and cleaned in the parts cleaner. Reassembled by oiling and greasing where needed. Replaced a few missing screws (clock and coin tube).
After assembly, I realized it was missing the bottom-most safety coin slide and spring. I found and ordered the slide from eBay. I had to weld the safety slide lever to make it about 1/8 longer to work with the new slide, then filed it down as needed. Cleaned and Tested before delivering it back to its owner.
