The total payout falls to the coin tray all at once? Wow!....lol
I'm so used to seeing hopper's push out one coin at a time.
Yep it hit the bar bar bar and "CHUNK" the trap door opens and the jackpot falls in the payout tray. Just above that jackpot is the "reserve" window, also filled with coins, but not quite as many. So my next big test was the next pull of the handle to see if the reserve falls into the empty jackpot hold, which it did. If the slot makers didn't have this reserve, the jackpot would be empty, and the machine wouldn't be at tempting to play, at least until it fills back up. This way, it's instantly "filled" and ready to pay out again to some lucky man, back in the 30's!
So at this point, the next coins played, with a full coin tube (for all other payouts) will divert and fill the reserve and the jackpot. I don't know which order... need to look inside at the mechanism in front. Still it's quite amazing how well these worked and were initially designed back in the early teens and even late 1800's.
