I just picked up a 28-2 that, as far as I can tell, was carried briefly and shot rarely, if at all. The cylinder face looks fresh and there is only one case head print that I can see, as if from a factory test firing. The finish looks factory original, so I don't think it was ever sent back to the factory for anything.

I mention that because the crane has a set of numbers on it that are different than the serial number. The SN is N5839xx and the number on the crane is 58xxx (can't remember, but they don't match the SN). Was this common on HPs -- to have a separately numbered crane? It also has a 3-digit number (S13?) etched onto the crane -- looks like factory work -- under the mystery number.

Just curious.
