Unless you actually know who bred this tortoise, it will be impossible to age. Although its not a youngster:0)
The viv is the worst place to keep a horsfield, as they don't do well in them. They need to be able to dig into soil at least 5inchs deep. They also need a heat gradient, 30-32c under the heat, and 25c ish at the other end. Which is near impossible to do in a viv.
NO OFFENCE IS MEANT BY THIS MESSAGE
I have never said I am an expert, but I do have over 30yrs experience with tortoises.
I JUST TRY TO HELP
