First engines by Franco Morini in 1956-57 were mostly the same as 1954-56 Moto FBM. They have very rounded head fins. The differences are: 1) the 3M head has longer fins, 2) 3M has a motor mount, 2) the 3M case has no front mount.
First hourglass logo was on the these 1958 engine covers.

New 50cc bore and stroke: From 1962 to 1978 Franco Morini increased the cylinder bore from 38.0 to 39.0 mm, and decreased the stroke from 42.0 to 41.5 mm. This increased the displacement from 47.7 to 49.6 cc. First was the 3CV in 1962. Then the 3M and 4M series changed in 1969. Then the S5 series changed in 1978. By the 1980’s all 50cc Morini engines had a 39.0 bore.

New: Left engine cover shaped with lines and angles. Right cover is still rounded.
New 50cc bore and stroke: In 1969 Morini increased the 4M series cylinder bore from 38.0 to 39.0 mm, and decreased the stroke from 42.0 to 41.5 mm. This increased the displacement from 47.7 to 49.6 cc. At the same time the rings got thinner, from 2.5 to 2.0 or 1.5 mm.
