Materials technology has changed a great deal in the past few decades, so I
am hoping (L-A-Z-Y) that there might be a flexible, nonsticky, spray-on
coating that can be applied inside and outside a large bellows (for 10X10"
enlarger).

For smaller bellows I patch pinholes using a material intended for those old
'soft top' hardtops of the Seventies. It applies smoothly, sets up flexible,
and is dead-black. But it won't fix this old bellows.

If none, then I think I might just send the old bellows to England to be
copied.

There are two bellows makers here in the US.

Universal Bellows,

Or you could look at the archive of "God Forbid No- I can hear your
screams now" View Camera Magazine. They had a article several years back
with detailed instructions on making a large custom bellows from scratch.

Personally I have used gaffers type tape to patch the corners of several
of mine.
