It's out of this bar in Exeter.

It's probably had an easy life.  From the model code I suspect it is fitted with a 500W and 1250W amp module (i.e. asymmetric design to bi-amp a mid-high cabinet).  You'd need to get hold of the second one they're selling, swap the amp modules around and keep either the 500/500W or the 1250/1250W amp
