There seemed to be grease around the Woods to avoid full mechanical contact
to the outer casing, greenish colour so may be leaching of copper or
something. Again emphasising that the 2.5mm run of Woods if near to melting
,
could have bent a bit while soft.
I'll have to slice open a new one (different make of course) to see if they
are made with a knecking to the Woods
This fused one marked (doubtfully relevant as seems to be a generic problem)
