Hello MMD.  I'd like to express my thanks to Matthew Caulfield,
Ron Yost, Ed Gaida, and all who answered my questions about the
Wurlitzer 165 tracker bar [080122 MMDigest].  Having located an
original APP bar, I now need to build the roll frame for it, and
I have the plans from Bob Stanoszek, and from Randy Charles for
building the 105 roll frame.

I believe that I read somewhere that the physical size of the 125,
150, 165, and APP roll frames were the same in all dimensions save
for the distance between the side plates, because of the longer
tracker bars.  Is this correct?  I'm unable to find the reference,
and don't want to mess up!  Would anyone care to measure between
the plates of an APP frame, or 165 frame?

Thanks again!
