Hi Frank,
Just a thought.........
Do you need to save the site, or the glass info?
Whilst artizana have been a significant gallery serving the south of Manchester and the North West,
unless you are selective, you might well find yourself getting bogged down.
Personally I'd consider asking for the relevant catalogues and images, to use for the Glass Study, and include a short resume about the gallery.
jmho,
Regards,
Marcus
