I can't read all the tiny writing. It seems like a Bakelite housing on the outside. Mad Dog

    Seems like maybe a later version of this one. Yours has two patent #'s listed, while the one below has only the one earlier patent #.

    Oddly, company name was actually Detroit Lubricator Company.

    Yup Detroit Lubricator.

    Funny name for an air vent but I have heard that name before.

    Apparently they made a "wide range of lubricating technology for steam engines…"

    It's an interesting device,if you look at the patent information.

    It appears to vary venting rates depending on pressure, slowing the venting under increasing pressure, and increasing it under low pressure. Looks like it belongs on a '32 Buick.

    Here's the patent:
