Hi James Matheson!  I am so glad to read that you have found
some papers from Harry and Sylvia Medcraft.  Harry was a radio
and mechanical engineer, and was one of the first people (in UK) to
build a roll-copying machine at home, in the 1960s, I think it was.

I and many other members of the (British) Player Piano Group fondly
remember visiting their home near London and watching his amazing
machine.  I still have one of their rolls.

Kind regards,
Paul Collenette
Exeter, Devon, UK
