and I had disassembled both the MT F7 and the Marklin F7. I do
know the Marklin's are geared higher (17:1 total). The whole exercise
was an attempt to figure out how they worked, and get some idea
of how to design small mechanisms. This was all about a year ago,
and I had to count the 12:1 reduction three times. I picked 12:1 because
that was the answer I got two of the three times.
