Blast from the past

Blast from the past

We were moving some manuals from the front counter to the upstairs storage room and found these pictures in one of the old Valley water drive books.  The date on the book was 1976, so these options represent some of the last versions of the water driven machines.  There are several of the reversible wipers still in use in our area.  The rubber tire option was probably a lot more rare, but still interesting.
