Also, if a pin is moved, it does not change its designation. For example, if the 10 pin were still standing and the 7 pin slid into the 8 pin position, converting this spare would

The lower operating and maintenance costs of the string pinsetter eventually led to the demise of free-fall pinsetters. When a bowling centre retires free-fall pinsetters, the old machines are usually bought by other free-fall equipped bowling centres and are disassembled for parts. Free fall pinsetters are still
