That appears to be an EPIRB. It would be good to know if it is the current generation (in which case it is worth something), and if it is registered.

Uh, I found this with about 1 second of Googling;
Personal Water Activated 121.5 MHz EPIRB
with In-Line Speaker
>Perfect for use as Crew-Overboard system when combined with
VectaTM2Direction Finder
>In-line speaker emits audio warble to confirm activation and
transmission of distress signal or to notify of accidental activation
>Exclusive ACR audio indication of transmission allows effective
> User-replaceable battery unit uses inexpensive, easy-to-obtain
common lithium camera battery Duracell DL223A (or equivalent)
>10-year storage life lithium battery
>Frequency stability exceeds ETS 300 152 standard

The battery will almost certainly be past date and require replacement at vast cost as it is not 'supposed to be' user serviceable.

Also I think that I read something about 121.5 no longer being monitored, maybe someone with the facts can confirm this.

So worth zero and put it on EBAY.

121.5 mhz is a very short range signal, which is homed in on when a SAR already knows to be looking for you. Modern EPIRBs use a satellite link that relay your distress call (preferably with your GPS coordinates) to a shore facility. This ancient technology is not very useful.
