Hello Fabio
B3A4293R is a good serial number.
B3 is the prefix for the H30-60F series
A is the manufacturing plant identifier for the Hyster plant at
Irvine near Glasgow in Scotland
4293 is the sequential number of the Irvine built trucks
R is the year of manufacture and is for 1971
The OE engine was a Perkins 4.203
At least you know where it was built !
