Hello all,  I am interested in converting a 1927 Weber Duo-Art grand
to the 4-port roll tracking system.  I have developed a tracker bar
CAD drawing from information kindly supplied by Patrick Handscombe.
Based on system description only, I also have a drawing for the
pneumatic control valve box, but...

Before I start building and modifying, perhaps some one has the
required components they would be willing to part with.  Any help
regarding available components, suggested tracker bar machinists,
measurements, drawings or pictures to help verify my drawings would
be greatly appreciated.

Thanks for the read.
