My son brought this home from the flea market. A good eye he has! I could not tell him what it is.
It is heavily built, and shows wear as from hard pressure against some hard surface along the edges Overall length 7" collapsed, 11" fully extended.
The screw is buttress threaded, with a rounded-bottom keyway along the length to allow it to slide past a pawl when rotated to the correct position. The pawl (or partial nut) s sping-loaded so you can push it closed regardless of the position of the keyway, but once the thread is loaded you can adjust against substantial pressure by turning the knob on the end of the screw.
There must be some purpose to the reliefs milled in the back. It is assembled with what look like #8 plow bolts and slotted nuts
In case the writing is not legible, the legend on the top or front sauys, "clean in gasoline weekly" (to keep the pawl free I guess). The number (S/N?) on the back is 23952
It is a very nice one of whatever it is.
