I know it's not a metal detecting subject, but I'm hoping there's some  budding scientist out there
who can I D  this " SHADOWMASTER  PROTRACTOR" that I recently purchased. It's
15inches x12 inches and it must weigh a couple of stone.
                                 What I need to know is
                        1 - what is it used for ?
                        2 - is it complete ?
                        3 - Any idea of value?
                        4 - Does anybody know anyone who buys scientific instruments ?

Thanks JCB, a teaching aid also makes sense, as the bloke I bought it off had some bunson burners as well.

It projects a silhouette of an item onto the screen (back projection) and then can be measured for accuracy. If the bit you have isn't electrical then I would say you've got bits missing Wink

I just checked, theres no place for any electrical connection, unless it sits on top of a projector.
I just realised it's made of brass, so it's a win win situation either way Grin Grin

There should either be a silvered prism or mirror inside to reflect an image up onto the screen but it needs a hole in one of the sides to allow the image to be projected on to the inside.
