RN 3 1132, Never did know what the RN stood for. All my friends had CLoverdale. Every once in a while they uncover an old painted sign on a building in NY when knocking down another building next door and you can see the old signs with those numbers. Some places of business still have the old signs up with those type of numbers. I have photos someplace.

Last week this sign was uncovered near my store while remodeling a building, but no phone number. I think it is from the 60's.
