Repowering a pair of hudsons

[jglfan]

I had forgotten that some Hudsons got elephant ears. I took a look for my NYC Power book, but don't know where I've left it. I only remember the Niagara's and some L4 Mohawks having them. I thought they were deemed not particularly effective so were not used on other types. I assume it was some of the J3's thet had them applied? Can you tell me how many and their #'s?

Thanks
