Thanks for the suggestions Guys.

The person I most suspect of leaving these in my workshop (but I am not sure) manufactures specialist transformers and coils etc.
Hope this may be a clue.

Fusible link maybe ?

Could well be that, thanks.

I knew I'd seen something like that before!
It's a ruler, metric, made in Japan.

Brilliant Matt.

looks like part of a tagging system.say you do some stator coils and you want to tag the wire pairs so they dont get mixed up.
after they dip and seal the coils they are removed during instalation as the leads are connected.

You guys are so dense.

It is obviously a round toit.

For people who have difficulty getting "around to it."

Sheesh.

I'm curios , what the hell is it?

Hi Ed,

Consensus of opinion (but is hasn't been confirmed) is that it is a fuseable link.

I still have not found out who is leaving them in my workshop because nobody will admit to it. (wonder if i could sell them on ebay)

twisted pair wiring? Doh......thread bend twist? Do I win? thats what I'd use it for, only if i had a wire tension spool twisting machine.
