Sorry Kev forgot to say, the arm rest is an Armster one.

They are a standard arm rest, and a car-specific mounting bracket. So the same armrest for every car, but a different bracket to fit it.

New they're usually between £75 and £100 depending on where you get them from and what car they're for. Almost certainly find one on ebay, just make sure you get the right one for your car and the right year as well... Mk1 focus armrest won't fit a Mk1.5 (facelift) and vice-versa.

Fitting it is simple, just a few screws to hold in place.
