This stapler is an older model and I can not find a parts diagram. A few months ago it jammed on me. I discovered the hammer cut staple in half which jammed the anvil from moving. In order to clear it I had to take the whole anvil works out. By the time I got around to rebuilding the unit, I had forgotten how it came apart. I have looked everywhere I could, without success. Any help in obtaining one would appreciated.

I would just go to HD or Lowe's and get a new one. How much is your time worth?
