Whereabouts of Fittings

I know of some locations where fittings from Olympic are held such as the Swan Hotel in Alnwick, etc, but I was wondering if anyone knew of all known locations of where Olympic's fittings are located. I know of the old hotel on the Isle of Mann which supposedly held fittings and furnishings, now unfortunately demolished.

Can somebody give a list of all of the known locations? I am really interested in this and would love to go to these places.
