My rule is anything 30 years old and never used likely never worked. I think that flash used a battery similar to the current 60 flash.
Click on the in depth and you'll see it mentions the 202. BUT email Metz tech support in Europe and ask. They'll know for sure.
IIRC you'll need a case for the battery and for sure you'll need a charger. By the time you've bought all that a used Metz 60 with all the fitings might be cheaper. A used Metz 45 almost certainly will.
