So I have a 235 that I picked up and am trying to decode the numbers.

The stamp pad at the distributor is Fo4I8A

is this just a serial number, or does it mean someting else/also?

Also, there are some other numbers on the head B55-848
850

The casting code for the head says its a 1956 head but what do these other numbers mean? Thanks in advance.
