could be used for removing caps from barrels, could
be a headset or bottom bracket wrench for a bicycle, could be for turning a
pully round on your motor.....any other ideas? Take a picture I'm curious to see
it
Of all things for that to be for, we had one similar to that in
the theatre I used to work in. It was for a specialty nut on a stage
light, you might see if there's something in your imperial that's round with
matching notches for it to fit in. No ideas past
that...
