There was a time in the 1980s when Schiedmayer and Kawai had a partnership. I helped a student buy a 49" Kawai back then that was better than the Kawai norm, very German in its clarity and tonal warmth; I was told by a tech that it was a Schiedmayer made in Japan and sold under the Kawai name. It was, and remains, a superb upright, better than any Kawai upright I've played (and I should add that I am a Kawai fan).
Years later, I encountered an actual 49" Schiedmayer made in Japan in the same era, with the name Schiedmayer on the fallboard. It was just as fine, and very German in flavor. Seemingly the same piano.
I don't think this Schiedmayer/Kawai partnership lasted long, or was ever well known. A trial marriage, that was more like an affair. I guess you could call these stencil pianos, but I like the quiet affair idea.
I do not know if this is related but I have just bought a Kawai upright KL502.
When I first played the piano I was completely amazed by the tone.It has an
extremely mellow tone .,it sounds like a European piano! This piano must have
been voiced like this by the factory.It was made in 1983 or 1984 in Japan according to
the Peirce Atlas.I would like to think that this Kawai piano was influenced by Shiedemayor
in voicing this piano in this way in the factory.
Fortunately the action and response of the piano is excellent as well.Although it is
a " grey" it has been in Vancouver for 22 years.It seems to not have been played very much.
It was a reasonable price as well.
Sorry for the distraction but this story of Schademayor and Kawai was just too
much for me. This Kawai piano is also a 49".
