I bought the fantasy set of Caesar, but I didn't get Gandalf. A bit annoying, as you are given two of various heroes, but none of others.
I do have Hobbits in 1/72, even without looking for them. They came with the Lord of the Rings boardgame, I received as a christmas present many years ago;
They look a bit big, but are perfect as medieval young peasants
.
Apparently, they have now upgraded the game, with more modern looking hobbits;
Maybe some 10-15mm metal figurines would do the job? I have a few vintage ones, which I use as kids for 1/72, sort of children crusades, as they are short and with childish proportions
