GG,

My question is about the depth adjuster on a #220. I've discovered that
Kunz was not the only German manufacturer who made iron planes. There
was at least one other company, Tillmanns & Maier in Velbert/Rhineland,
who used a somewhat different numbering system. I have a block plane
marked #2200 presumably from this maker, which is a copy of a Stanley
#220. Just last week I bought another #2200, which has a different
adjuster. Here is a picture of the two planes side by side (the plane in
the back is missing its knob and part of the lever cap):

This is the #2200 with the new adjuster. The screw has a large head
which rides in a slot in the casting:

Another view of the two different adjusters:

This is a drawing taken from the related patent from 1959 (German patent
No. 1782418):

This patent actually was my first pointer to this company. Now I also
have the plane. What I would like to know: Is this the only maker who
used this kind of depth adjustment? Or is there a similar US patent and
a plane made accordingly?
Thanks for listening.
