M1917 stock with a "T" makers mark

[Merc]

I acquired a really nice M1917 Winchester recently with an early serial number 65030. The rifling is crisp and the rifle's general condition would indicate light duty throughout its life. The stock has been replaced at some point in time with one that has a "T" makers mark stamped on the front end where you would expect to see a W, R or E. I am not familiar with this manufacturer and I am not seeing anything on the Internet that would shed any light. Does anyone have any information on, or can identify this company?
