I need to replace a spring in a Brunswick Model 105 tabletop. The arbor end has the pear shaped hole and the barrel end has both the pear shaped hole and a rectangle shaped hole. I'm not sure why. It was attached to the barrel with the pear shaped hole. Anyhow, how long of spring do I need? Thanks!!

It is best to call Ron Sitko on this. He has all the details on mainsprings and is the best supplier for them.

Spring is usually about three months long.
