Unusual Weighted Percentage Device Found On A Watling Rol-A-Top Mechanism
Earlier this year I posted some information about antiqueslot machine percentage devices or more commonly known as “bugs”. The article was titled Bugs In My Antique SlotMachine. I followed that up with a short update on a Mills Novelty slotmachine bug we found in a machine a few days after writing that article.

Since that time, we have found numerous other bugs in machineswe have gotten in for repair and restoration. Most of them are a similarconfiguration and do the same job – preventing one of the reels from stoppingon the jackpot symbol.

Watling Rol-A-Top Restored By Nations Attic

Watling Blue Seal Slot Machine

Last week I did run across a rather unusual percentage deviceon a Watling Rol-A-Top we were restoring. As shown in the photo above, thisdevice bolted to the outer ring of the reel. While this did not prevent thereel from stopping on the jackpot symbol, it did add quite a bit of weight toone section of the reel. This weight would cause the reel to want to stop in anarea where the jackpot symbols were not located. This sly device was not foolproof but it still did the job of throwing off the number of times it wouldland on a jackpot symbol.

It should also be noted that it appears Watling went out oftheir way to provide pre-drilled spots on both the reel tins and inner reelstops. These pre drilled holes made it very easy to install a bug in seconds . Generallythe other slot machine manufactures would never put these on their machines butWatling seems to have rolled out the red carpet for percentage device installation.Watling slot machines, specifically Rol-A-Top’s, are notorious for havinghundreds of different small and large changes to the inside and outside oftheir machines. While these “bug holes” may not be in your Rol-A-Top, I’m sureothers out there have some equally interestingly unique features! Don - Nations Attic
