US Navy Pitometer origin/value 1945

[Plantguy7]

Hello guys, I came across this item and was hoping I could find some help here identifying it/ assigning a value to it. It's a Pitometer made in 1945 for the US Navy. All I know currently about its history is that some guy grabbed it off of his ship before they decommissioned it. The person who gave it to me was his son, who really could care less, so didn't know anything about its history. Anyways, pictures will be posted below, along with what it says on the information tag. Any help or info would be greatly appreciated, thanks in advance!

Have you seen this?

As far as value goes, I would imagine it's pretty low, perhaps a lot less than 100 bucks, but you never know.
