Requested a letter for a Winchester model 1886 I purchased a few years ago. The rifle was rebarreled with a factory winchester 24" lightweight barrel in 33 wcf and the magazine shortened.
According to the letter the rifle was built in September of 1891.
Type: rifle
Caliber: 45/90
Barrel type: Round
Trigger: Plain
I had a pretty good idea it was a standard round barrel rifle just didn't know what caliber it was. I like knowing now what it was originally.
