Wow - I worked on the Bowlmor rubberband duck machines at Village Lanes in Pgh. One funky machine. Like an erector set compared to the Brunswick 10 pins we had. The pie was the thing that dealt with the pins, the sweep was the bar for clearing deadwood - ran on this chain in channel.
@@DaDaPaMCIt’s a Bowl Mor. That company made the most popular candlepin machine. There’s still a lot of them running today and it’s an excellent machine. Most of the duck pin lanes have Shermans.
