I think this might be a saccharimeter.  I checked both eyepieces using a piece of polaroid and each of them contains a polarising element.  The label on the base says “Griffin & George”. There is an extra label below this, that states “No.7709″.

Vector Scale Diagrams from mr mackenzie on Vimeo.

If you want to improve the accuracy of your scale diagrams;

• use a sharp pencil
• measure the vector lengths as accurately as you can
• make sure the point of your vector arrow is on the end of the measured line
• start each new vector right at the tip of the previous vector
