It's an Australian made Ainsworth Aristocrat, Harvey Gross had many different slot machines made by various manufacturers in his casino!
I've had a few of these style machines go thru my shop, one below which was a four reeler!
What questions do you have?
I don't spend a lot of time on my computer so I very seldom drop by the forum, too busy in the shop with service work as well as parts sales!
This slot machine was placed in the main casino, Harvey's Wagon Wheel back in the day as I started my casino work in 1965 in the Sahara Tahoe next door to Harvey's after the Sahara opened I had spent some time in Harvey's, the Top of the Wheel was a great local hangout!
Ciao!
