tv175 cylinder identification :

i have a cylinder with 62,6 bore and the walls are 3mm+ thick.
other identifaction possibilities ?
special measurement of the fins ?
unfortunately i have no 150 cylinder here to compare the spigot with this one.

cheers,
sp

Well, it won't have a notch in the top fin, and that's about the extent of my knowledge on the subject I'm afraid.
