Mysterious (possibly original? Cornell Dubilier Beaver) capacitor not in schematics

I can't see that the one you removed is 12uf, the numbers on it really don't make sense.

does it SAY 12uf on the part?

Yes it does, sorry. What I pictured was the category number of the capacitor from CD BR type capacitors (1215 = 12uf, 150V). It also states the ratings outside of this category number. Photo was mostly for identification purposes and showing age, my apologies.

I have never seen a code like that on a electrolytic capacitor before :O

Only reason I was able to find it was from this gem circa 1938… maybe that’s why!:

"dry electrolytic" that's why, not come across one yet, from what I hear, they very rarely fail, they can, but not like the normal electrolytic caps.
