it looks ok to me...i have one that is about 15 yrs old and as its in a small pot, it doesnt look that much bigger than yours and it gives me about 15-20 figs a year. it may be worth digging down to see if it is in a sunken pot as they remain relatively small but produce decent figs if they are restricted....i believe.
If it isnt in a sunken pot, it may be worth digging it up and potting into a 14 inch (ish) pot to see what happens. Nothing to lose really, but if it is left in the open ground, it think any fruit will be small and not worth the effort.
Nothing like a freshly picked warm fig....YUM!
