    I rescued this today , a B & S surface gauge. It is tiny, only about 5" tall. I am unsure what the other device is on the riser. Could someone help me out ? The tool bit in the pic is 3/8" square, for reference. Its sitting on top of my friend's tailstock.

    Thanks, Tom

    Hi Tom,
    nice save!
    the first tool going up the mast is a scribe,
    the second tool is used in conjunction with a dial indicator to indirectly indicate holes that a dial indicator may not fit into.
    it could also be used to indirectly indicate the od of cylindrical objects as well, if the need arises as well- with a little forethought.

    That arm looks to be used with a back plunge indicator, not sure how a normal indicator would mount without the "L" shaped part to hold the 3/8" stem.

    That's correct Andre, it is used with a back plunger type indicator.
    there is a bracket missing that would hold the indicator to the horizontal mast where the hole attachment lies, like this:

    I picked up a larger B&S surface gauge some time in the last year. Just the base (magnetic) and the mast. Your photo will be useful when I get around to making the missing pieces.
