while back I purchased a Stanley 67 spokeshave (the one with the beaded
rosewood handles) at a garbage sale and it has the flat bottom installed.  I
looked in the books and saw what the round bottom looked like and thought -
that’s a lost cause.  About 2 weeks later at a local flea, I found the round
bottom in the bottom of a box - 25¢.  So instead of a box , I used a piece of
string which is another option.
