Re: International Marconi Day at Oxford Science Museum
There is (or at least, there was la few years ago) an on-line catalogue with images of most of their items. Nearly a decade ago I did contact them about an item incorrectly labelled as a giant radio valve that is in fact a large bipost-base photoflood lamp bulb of a specified colour temperature, but they didn't seem interested and it was still incorrectly identified the last time I looked.
