A COMPARISON OF THE ORIGINAL FORM OF 'NEW MICROSCOPE' OF POWELL & LEALAND WITH THEIR LATER 'No 3' MODEL
MAKER: POWELL & LEALAND
The slide holding parts on top of the stage changed from a single wide sprung slide holder to a form with two small plates sprung on the right and left sides. In addition, instead of a short flat fixed bar, with an accessory bar to increase the height of the gripping parts, the fixed bar became L-shaped to permanently provide taller gripping points. In the older model, an accessory insert could be used to provide taller gripping points for the fixed bar at the user's discretion.
