Hello All,
How do I go about determining the size of a broken mainspring so I can find a replacememt ?
The watch is a 1920 Elgin 16s 19j grd.455 b w raymond ser. # 23129535.
Thanks, Don

According to my Elgin Parts book, that is a Grade 455, and the Mainspring is 817. I will send you one for a $15.00 Donation to the IHC185 operating fund

Dave,
Yes, please send me the mainspring. Also send instructions again on donation process.
Thanks for all your help.
Don
