"actually, i dont believe the handle is meant to be put in that position. I show it resting of top of one of the uprights, but it also goes in the other direction and would not rap your knuckles. I dont believe anything is missing. thx"
I have no idea what this is. Its all wood except for a thin tin strip on one side of one of the upright pieces. When the handle is moved the bottom piece just barely clears the center upright. The bottom base is 11" long by 2" wide. I think the tin strip might have been a guide or stop of some sort.
