Quoted from vid1900:I'd skip the dummy wheels.
They look good when hidden behind the backglass, but look silly when exposed as the scam they are.
How about clear ones with frosted zeroes? It seems like a lot of work was done to faithfully recreate the whole machine. It seems like a shame to have something left off that even casual players may notice. \
Just a suggestion. I am in awe of how this turned out and missing dummy reels doesn't really change that at all.
