Thomas Price was one of the 3 home owners on the 1858 Martenets Map. Good guess wainzoid!
I would have to say the symbol is the letter "T". 20th letter in the Engish alphabet that falls between "S" and "U" and stands for a sharp, constantant sound formed behind the upper, front teeth using an exhilation and the tip of the tongue dropping downward.
It looks like the business end of an automatic press buckle. Is that some belt still in it at the back perhaps or just mud? I think the symbol is just a T (for personalisation) rather than a clue to its manufacture.Does anyone recognize this symbol?
