Jim BielefeldtIllinois mainspring part number
Hi Hi
I am in need of a part number for the mainspring
for my latest addition . During cleaning I noticed that the mainspring was broke in half. I would like to replace it, but I'm not sure which one and cant find a site with the info. The serial is 1811996. Thanks in advance.

David AbbeThat should be Illinois factory catalog order number 6840, part number 124, or catalog order number 6841, part number 573. Either should work.
