3151: Heavy-duty backscratcher? The square shaft section
near the handle might be for a wrench to apply torque, so
it could tighten/tension wire or rope or strapping.

3152: lid flips open on cotter-pin hinge, the handle operates
a catch on the mechanical part we mainly don't see. Probably
a forward/reverse/off kind of control? With another handle?
That suggests elevator or hoist.

3153: hand-operated vacuum pump?

3154: an 'ah-so' style cork puller

3155: A light duty drill press, but the control lever is odd.
Limited up-down range, no drill marks in table, so maybe it
was a fixtured gizmo (some kind of hold-the-work elements are
missing). Jacobs chuck could hold a variety of tools.
It'd work as a factory station for deburring or countersinking,
with an oddball (foot?) control for the up/down. Of course, it
could also bore corks or put holes in belts.
