Three number Combination Working Wooden Padlock.
I made some of these a while back and had to make some more for grand kids.
The first one is made from a solid block of hard maple with a pine shackle and buttons.
The 2nd on has been dyed using black walnut stain.
Finished with 4 coats of MINWAX Clear Gloss Polyurethane.
The plans came from "Making Working Wooden Locks" book by Tim Detweiler.
