in 1910 Moss numbered blood types from 1 to 4. (Often written as Roman numerals)
1 is AB 2 is A 3 is B 4 is O
Dog tags of Australian soldiers apparently used both systems for a while.
The number system is confusing because Jansky also used numbers to identify blood type but the meanings of 1 and 4 are reversed in the two systems. Jansky system was primarily used in Russia and Eastern Europe.
A 2 is also confusing since there is an A2 blood subtype.
Those are all very interesting replies, but it this case it turns out that human error was in play: I was shown the dog tags yesterday, and they were clearly stamped O POS (1947). so all I can think is that this gentleman once saw on a medical record elsewhere O + and he misread the + as a 4. So no problem. thanks to all of you who replied.
