Many years back, bought a couple of Ficus from Tesco - like minature trees

Odds on they are Ficus benjamina. See:

This implies that the parent was a tree of significant size.

Which brings me to wonder if all are the same plant/tree - I had assumed
that I had a minature version but perhaps what I have is a couple of
severely pot bound trees.

Yup - see that article :-)
