I have a brass saddle square that came with a set of mid-to-late19th
century English sash joiners tools, all bearing the S Bradshaw owner's
mark. Also in the box, though bearing a different owner's mark, was a
saddle miter square.

Both tools appear to be user made, so perhaps they weren't commercially
available until a little later.
