    It is a Vivitar, It looks like an old 283, but instead of a round sensor
    dial, they have a slider. Because it is identical to my 283 in every way
    but the round sensor, I'm deducing that it is an old Vivitar 283.

    I wouldn't use it on a Digital or a modern electronic SLR, due to probable
    high sync voltage. How does it work? Have you taken it for a spin?

    Like all the best photo equipment, this flash gun came from the thrift
    store. It has 'use Vivitar SB-4 power supply only' stamped into it,
    which is how I deduced it's a Vivitar. The name plate on the front is
    missing. It looks a lot like the Vivitar 283, but without the sensor
    disk thing on the front, and no place to add one. It's essentially the
    same body.

    I haven't been able to find any reference to a 283 with no sensor on the
    front, so I'm asking here. Can anyone ID this beast?

    Thanks in advance.

    (If only folks were as obsessive about flash units as they are about
    lenses and bodies, I'd have already found a dozen web sites telling me
    everything from guide numbers to what other products it was intended to
    compete with. <grin>)

    It didn't fry my DSLR, and no smoke emanated from the film camera. It
    works fine. It even had fresh batteries inside when I got it.

    I have to admit some degree of ignorance about, or at least lack of
    experience with flash photography, so I'm not ready to show the world
    what happened when I 'took it for a spin.' :)

    It looks like my Vivitar 273 with the nameplate removed.
    I think it was a slightly cheaper version of the 283.

    Even with a high voltage, it won't damage instantly, but it certainly could
    in time. I would measure the sync voltage with a multimeter or voltmeter,
    before continuing to use it.

    That said... 290V is a lot of juice.

    Thanks to everyone who answered.

    Indeed this is the Vivitar 273, which was actually introduced before
    the 283. The 273 was relatively successful and Vivitar improved it with
    the 283.

    The Vivitar 273 has a trigger voltage of between 270-300volts..

    Far too much for modern computer cameras..
