I am looking to sell this instrument, but it has no part numbers or any other identifying marks other than it says "Kollsman" on the back. Anyone know what it is and what it might be worth?

1$\begingroup$ Both needles are pointing to -5 in a 1G environment, which suggests to me that perhaps the instrument may be broken. One of those needles should be pointing to "1". $\endgroup$– Dan PichelmanJan 28, 2021 at 12:43

As the face says, it's a "G meter", aka "accelerometer". It measures vertical acceleration in units of "G" (i.e. acceleration due to gravity, 9.8 m/s^2 or 32 f/s^2).
Price would vary, but here's a site with a similar instrument which sold for $75 when it was in stock: https://aeroantique.com/products/accelerometer-g-meter-1?variant=39681371274
