Welcome to Richard Kemp.  Good to see another subscriber in the UK.  Some
ideas that may help you.

65n rolls are commonplace in the UK.  Nobody much wants them so they
usually sell for very little.  I have a horrible feeling that some even
go in the dustbin.  The Player Piano Group runs a postal roll auction a
few times a year and there are always some 65n rolls.  It is worth
joining the PPG.  There is a quarterly bulletin, roll auctions, social
meetings etc.  The membership sec is:

    Malcolm Billingsley
    80 Montalt Road
    Woodford Green
    Essex IG8 9SS
    0181 505 1850

The other UK postal roll auction is run by Frances Broadway.  0171 254 6145.
There is an annual sub of [=A3 Pound Sterling ?] 2.50.

Good luck with your project!

And a note to Jody.  We like the digest.  Please keep up the good work.

 [ Thanks!  Jody ]
