Last night a friend was asking about all the old molding planes I had, when I was looking in the tool chest I acquired about twenty years ago, I came across this.
It was interesting enough to model and I believe it does fall into the "woodworking" category.
The lower top handle rotates free-floats from the top one. I can't think of one reason why. Does anyone here have a suggestion why?
