That is beautiful , Wow
Do you know the correct colours? , really nice job on the paint as it is though  
There was a few  of these at Echuca in Vic , The cards were worn down on one side i remember , Could be fixed with a little edge of Mylar maybe.
Hope you can find the right cards , or other sets of cards , just make more "Toppers"  
 Nice find Daniel .
 These games were all  badly worn out by Queenslanders on holidays    
 Drinkin beee !  and grinding the handle...
