Proportional dividers

    The   base design is very old ( 150 years?  + ?)  .  The Bridge city
    one is a tool made to be  a pretty  and  has  very well  built
    position locking.  I have one but didn't really need it.  It is the
    third one I have bought.    The first was in Tokyo about 50 years
    ago and  things there were very cheap  then even with army pay   (
    may have been about $3   US equivalent  then) .   The second is a
    little larger and was bought in the US   about 30- 35 years ago  for
    at least  $100.   They were and still  are very handy  for scaling ,
    but there are other easier ways to scale stuff now. Computer design
    programs , scanners and  variable size  photocopiers  can do the
    job. There never would have been a big market  for these.   Easy to
    make in a crude form . The preset  balance points make the BC one
    much more useful but harder to reproduce  at a competitive price.
