Man, it's just gonna be a cheap 8-Ohm speaker; if it's 1980s, probably from Japan, MAYBE Mexico or China. You can get them just about anywhere. If you have a really old desktop computer sitting around, you'll find one inside the case.
Here's a 3" from Adafruit.
Here's a pair of 2".
If you're looking to replace the speaker inside that flashlight/radio, you're going to have to open up the case anyway, so what's holding you back?
How would one test this if they didn't happen to have a Ham radio? Umm, I guess there's this thing called the internet and it can be searched...

8-ohm speaker = amazon
1-megaohm resistor = amazon
insulated, solid-core wire = amazon
I'm sure someone can find a better choice for a small spool of wire!
