B&D trimmer w/o charger (Western Dearborn)

I loaned this Black & Decker hedge trimmer/grass clipper to someone and when I got it back they lost the charger. It is a NiCad battery and the new ones are all Lithium so I can't find a replacement. I am posting this on the chance that someone has a charger for it. This was lightly used although it must be at least 15 years old. It needs a 7.2 volt NiCad charger and on the device it says it needs a 5102404 charger.
