Hi ??,

Welcome whoever you are, but I have one question. Who are you?

I don't know for sure, but think maybe your Thos. Tillotston & Co. was a
British maker; I obviously don't know when he worked or if his stuff has
any special value, but doubt it. Not sure where you got the early 1800s
dating; might that be from a crosswiring with a T. Tileston who was an
early 1800s Boston plane maker?

Best Wishes,
Bob
