    mystery device

    hi everyone,

    I inherited this thing from a box of milling cutters and can't figure out what it is...help!!
    It's about 6" overall, has a split shaft on top that looks like would hold a pencil or scribe, this is attached to a spring inside the square shaft. Turning the wheel moves a pointer inside the scale slide with 50, 100, 150, 200, 250, 300, 350, 400. as the dial gets to the higher numbers the spring tension increases. The only marking is on the back "4223L". It even foiled google image search as it thinks it's a syringe. If anyone can identify it would be much appreciated.

    cheers stevoh

    Thanks for everyone's input. This 'thing' is made from nickel silver, even the screws appear to be same, here's some more pics.

    It looks similar, though not identical, to an automotive belt tensioning gauge...

    Try placing a small scribe in the "holder" end and see if you can push it against the spring: it looks like an adjustable durometer for testing the "hardness" of semi-hard materials, like rubber.

    It's a scale to weigh trophy sized anchovies.
    Maybe.

    it looks like adjustment knob for the milling drums. it controls the microns acceptable after particulate materials are milled. 400 microns for example.
