I have an older plane and would like to know the manufacturer. I tried
google but am not getting good results.
The base is 2 1/2" x ~9 3/4 rounded in the front and an ogee in the
back. The black handle and knob are plastic or maybe bakelite. Around
the knob is cast "USA No 4", nothing else that I can see.
It looks very similar to this:
but doesn't have a short screw at the base of the handle (#15), the
handle can twist slightly between two stops. It also doesn't have the
notch at the back of the base.
Cast into the lever cap is "SoJo", this is throwing me of on the google
search because "SoJo" alone generates over 1mil hits.
Any help would be appreciated.
