Line Mar Match Box Construction 099 - Pump

I found a Line Mar Match Box Construction Set from the 1930s, complete and with instructions. The box claimed the set made 100 different toys. I decided to test that claim -- one toy at a time. You can read all the posts for the Line Mar construction project at 100 Toys.

099. Pump

This toy didn't take a long time to build. But it did take a long time to puzzle out. As always, the illustrator took some liberties. The 3-hole girder that serves as an eccentric crank doesn't fit as drawn. 

I'm still not entirely sure I have the string positioned properly, but it's as close as I could come.
