This is a copy of a 073-type shoulder plane. I have done my best with creating it, but as I don't own one, I am not really sure about it. If someone downloads it and checks the dimensions etc. and would like to correct me on them, I'd appreciate it. Otherwise, this and my others (as well as some forthcoming models) are hopefully useful for people designing tool boxes, chests etc. Also, hopefully for learning how they work.
