Odd Electrolytic

[jeyurkon]

In making a list of capacitors to replace in a 1949 Sylvania I came across an electrolytic in the AGC section that is rated 10Mfd -12V, 150V. Looking at the circuit I believe it actually can experience both polarities. Other than non-polarized electrolytics I've never heard of such a thing and those have equal voltage ratings.

Have any of you come across these in the past?

I think I'll replace it with a metalized polypropylene if there's room.
