Machine #3 - 66-4

So I had toyed with the idea of converting the current rebuild 66 machine to be a treadle.  I guess that's off the books for now.  This 66-4 is from 1925, a year older than the rebuild one.  I'm up to three 66s, same number as I have of 15s.  I'm thinking I'm keeping all of the 15s though.  The 66s will go to the back of the restore line after I finish with the current one.
