COMMERCIAL ROOM



The commercial room contains a number of interesting technological
items from the 19th and early 20th centuries.




We have a large range of early phonographs, records and cameras




This is part of a large range of typewriters and copying machines





An old telephone exchange with radios





Shown above is an early movie projector that used a carbon
 rod arc system requiring great skill to control otherwise
the film would catch on fire.




This room is a must for anybody interested in technological change
 over the last century
