I contacted Cody for a letter and this was what I received back:
"We are able to provide the serial number application (SNA) factory letter for your Winchester. This letter will contain the
date on which work began on the firearm. Configuration and customer records are
no longer available for your Winchester".
Anyway the gun came out of Northern Vermont and a previous owner worked for the railroad but thats all I know so "
gbro" may have figured it out. I know this is nearly impossible to track but it is always fun to search. The only other thing that stood out is the marks behind the hammer.
