So do you think the fuse could have been physically damaged, rather than
blowing?

By the looks of the picture the fuse detonated with considerable force.
I expect an insane current flowed briefly. It may do so again if the
fault was permanent as opposed to a transient dead short of the output.

A lash up with a 3A mains fuse is worth a try but be prepared for the
magic smoke coming out or worse. You don't want it starting a fire.

I'd conduct any tests outdoors and wear eye protection. YMMV
