Many instruction books for the Morgan Plus 4 (1950s and 1960s models) have fallen apart over the years from extensive use or simply got lost.
 
The USA Morgan agent ISIS Imports was allowed to reproduce these. The books distributed by them were based on the TR4 engined +4s, but had an addendum with engine specifications for the earlier versions. This is the early version which has green letters on the cover.
 
The entire booklet counts 52 A5 size pages.
