Hello fellow l'isters!

We are doing an exhibition titled "Light: Art, Technology, and Society in
the Industrial Age, 1750-1900", and we are seeking  (either by purchase or
by loan) various early scientific lighting instruments, in particular
Geissler tubes, and Crooks platinum foil tubes.  They must be in working
order and not reproductions.  Does anybody know of anybody who is sells such
things - or willing to loan these types of items?

I've enclosed a description of our exhibition as well as the link to the
preliminary web site:
 <<description.doc>>

Any help would be immensely appreciated.

Thanks
