Win 1885

I’m gonna throw this out there, cause I’m exhausted from searching for somthing I don’t think exist…. I’m sitting on a bunch of Winchester 1885,s.
After what seems like several years f searching I. At a dead end.
Question: Can anybody here, steer me to someone who can machine me a base, as a Picitinny rail for a Winchester 1885???????? The only thing I find is a Talley or Leupold set up.. weary from looking …Thanks. Tom
