I like the heat gun idea. Possibly screw the plate to a piece of wood first to make it easier to handle when hot.

Any similar plate of that era will be black printed with similar ink so experimenting with a scrap plate from something else would tell you how much you are risking the black by using a particular process. I certainly agree that it would be very easy to scratch the plate with any kind of metal tool but possibly a plastic tool (PVC, not acrylic) would outlast your finger nail.

How about a hot water pressure washer ?

Robin.

Try your local Auto Body Supply Shops for tools that are used to lift the modern glued on chrome letters and numbers from body work without damaging the paint. They are usually nylon and the good ones come with various shaped edges and are big enough to get a good, controlled grip on them with your hand.

One of those tools will be a big help on your data plate, with or without a heat gun.
