I found this code on my head; 9610923010, I've found out it's a 1360cc TU unit - in my 1.1 Junior...
But from exactly what car? After the above numbers it reads "21" but underlined.
It also has 3 circles in which the following are stamped; C then 5 (or C5) and 11 then 93 with no circle, which I guess refers to the year?
Also, it's on a Weber Carb and has a 55mm manifold.
Hopefully someone can shed some light!
