These are the microphone shells with internals remain after I robbed them of their microphone leads.
They were new microphones that were supplied with a couple of Amateur Radio transceivers I bought on ebay.
Sold as spares & repairs, they have been sitting in a box in my attic for a few years.
I am loathed to throw them away, just in case they maybe useful to some one.
Weight without any packaging is 240g.
