If you find Gottlieb Snow Queen on IPDB you will see that the game has four score reels per-player. But if you look at the very last picture on IPDB you will see an example with five score reels and the picture is labeled "backglass converted to 5 digits".

Does anybody know about this conversion? Was it done at the factory or was it offered by Gottlieb as a conversion kit? You would need a different backglass to accommodate the extra digit.

I'm asking because I sold one of these a while back and it had five digits, somebody asked me about it after I posted this video in the sale ad:

Thanks! I never knew that operators (American or European) did that. Looking at the backglass you can see that the player1 extra digit goes-into the game title so some of the game title is missing... I honestly never noticed it when I had the game, it wasn't until after the sale that someone brought it to my attention. I don't recall it looking hacked at the time. I guess operators would have had to scrape-off the silkscreen to accommodate the extra digit and touch it up?
