The tool display

An original notice containing five intentional errors.

The display are being arranged to show different stages of one making process. Visitor's may uses the introductory information to follow the proposed sequence or examine indivdual examples in another order. The orignal tools will remain inside their supports. Please ask the guide if a function is unclear instead of moving an object to test it. A separate demonstration uses modern equipment chosen for that purpose.
