[GreenKeys] Wanted - dead 28 printing tape punch hammers

[Pete Lancashire]

If you have the remains of a 28 tape print hammer please let me know.

I am arranging to have the material analyzed to confirm if it is Delrin(r)
and if so what variation. If not Delrin, may be able to at least get close.

I don't want to a good one since the analysis will destroy most of the
material.
