Hey 3B enthusiasts!

I have a 57 CJ-3B With what I am 99% sure has the original engine because my father purchased it from the US Border Patrol in 1970 and never changed a thing since.
The thing is that the number 4FR 188089 seems to be among only very few in the data base that start with 4FR. Can somebody tell me what this number means?
