David, Bob, et al, When dealing with a Mehlin, make _no_ assumptions as to what might be considered to be "correct" - either as to piano design theory or the execution thereof. Mehlin, with Mathushek, Frank Weber, C.F. Stein (and, of course, a host of others in earlier years) was an original thinker. I have seen many of these things over the years, and they seldom seem to have been much the same from one year to the next. (Well, ok, that _is_ an exaggeration.) With the various fires/other damage in the Patent Office over time, it is not even clear how much of the original thinking (as documented in such filings) is still extant. If it looks original...really original...then leave the design alone, and save yourself a bunch of grief. Best of luck.
