U11 and U2? Do you mean "Baby Torch" [1] and "Standard Torch"?

I've never heard the terms "baby torch" and "standard torch" but I can
vaguely remember U11 (C), U2 (D), U12 (AA).

I remember AAs as HP7 or 'Penlight'

The original penlight batteries often consisted of two cells in one
paper sleeve, for the original pen light torches. If you just wanted one
and the shop didn't have singles they would break the double one in half
for you.

When they started the "high power" (zinc chloride) U12s they called them
U7 rather than HP16 for some reason; later HP7.
