Perhaps Preston was just capitalizing on something that was long used by
tradesmen - wooden mitre guides of the type illustrated in Zach's photo. It's
not a big leap.

I have at times resorted to a short piece of aluminum angle cut square, for this
purpose. That works well on construction lumber with rounded arrises, not on
sharp ones, due to interior rounding.

Old eyes have come to rely on this one: https://www.leevalley.com/en-

That reminds me, Preston made a mitre (miter) square. It is sort of a saddle
square.  I have a copy made by Smallwood in England post-Preston (never
found a need to use it yet).  I think Footprint also made them in the 1970s
or so.

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.
