John,
Thanks for the suggestion, I've got a thousand of the things so I have no
problems testing one or two to destruction. However it might take a little
while to rig up a power supply etc., I will give it a go and get back to the
group. No there are no markings at all, not even an indication of a band or
dot to mark the cathode. I too thought they looked like a rf package which
is why I bought them.

I think that the crossbar on the lead marks the cathode. I could be wrong,
of course, in which case it marks the anode.
