Can anyone point me in the direction of somebody who can supply me with
an _original_ (or a very good copy of a) French style, steel, bow top key
for a key wound music box?  The size required is No. 18 which I believe
is 6.75 mm across the flats, or a No. 19 which is 7 mm across the flats.

If someone in the USA who can supply this, my son's head office is in
Philadelphia and it could be sent there to save importation problems to
the UK.  Any information gratefully received.  Thank you.

Regards,
Roger Kempson
