Thanks Will . . .

I did not know that this design was eventually patented. Many over the years have used the 'patent pending' language to prevent copying without ever bothering to follow through and apply for the patent.

It also unlocks the mystery of the initials C.A.W. short for "Charles A Wefing" . . .
C.A.Wefing Patent circa '52

Your post made my evening!
