R E M A R K S :
---------------
This  AMERICAN ADDING MACHINE  came  "worn-out",  not working  right.  The
photo above is taken  after hours removing 100 years  of accumulated dust,
cleaning, benting back gears & levers, oiling,  restoring  display wheels,
... The simple repaired MAIN-HANDLE is now replaced with a better one.

The dented  FEET-HOLDERS  had to be removed to straiten the bent socket of
the machine. Its broken  RUBBER FEET  had to be replaced  by  4 FELT-PADS.
More brittle "METAL TONGUES" broke away in this procedure ...

      

                      ... Now the FEET-HOLDERS are fixed with reisin glue.
