I'm no expert, but I do have 5-6 machines. Original machines from casinos from that era
have lock with hand filled jackpots. If casino states jackpot is $6.50 that is what it had to be.
automatic fill will never be exact, always will be over or under stated amount. Golden Nugget
originals have nuggets gold, girls are silver. I would say your red machine is repoduction to
look like Golden Nugget machine. I have a black repo Golden Nugget. Not an original, but
still one of my favorite machines.
