25 watt UHF, either 403-430 or 449-470MHz.

Determining if it's the 403-430 or 449-470 requires either reading the radio with RSS or opening it up and looking at one of the PC boards.
Likely it's a 449-470, but not guaranteed. 403-430 was a pretty limited market back then, so they tend to be a bit rarer, but not unheard of.
So, what can you do with it?
70CM amateur. It'll take a bit of work to make it go far enough down into the band to be much good.
GMRS, would make a good mobile, but I can't recall if these have the Part 95 certification that makes it legal to use.
A good receiver for UHF stuff, although…
It's probably a wide band radio, which makes it not suitable for any sort of business or public safety use. It'll work as a receiver, but the audio will be a little low.
Looks like it has the 16 pin connector on the back, which is useful for adding some accessories.
If you were to go looking for one of these to buy, you could easily find one for $10 or $20 bucks, if not someone tossing them out. Since the narrow banding mandate hit back in 2013, most of these wide band radios are pretty useless to everyone but the amateur operators or GMRS.
