Radio Shack Micronta cat. no 22-203B 30,000 ohms/volt multimeter in box & Manual

READ!!!!! RARE. VINTAGE 30,000 OHMS 18-position Range/function Built in overload protective circuitry Easy to read mirrored meter with color coded scales Everything on the outside looks great, I put two new batteries in it but the old batteries had some corrosion and I tried to remove most of it! The pen light battery port has two wires (neg) that separated from the base and would need to be soldered back to connect with the battery! I don’t have a soldering iron! I am not sure if it would work otherwise but it seems to be in good condition as far as the aesthetics! Might be a great project for a geek or electronic nerd!!! I wish I was one! lol!
