John's Virtual Museum of Interesting Gadgets
 
 
 
 
 
Welcome to my virtual museum of interesting old gadgets. 
 
Many are measuring instruments - some quite ancient; some more recent. But there's other stuff as well. You will find the collection listed by category on the sidebar. Larger photos can be seen by clicking on the thumbnails. Where I have handbooks or other information I have included a PDF or zip version on the relevant page.
 
I hope you enjoy your visit to my virtual museum.
