Mick's got to find stuff to fill his newly painted cabinets not sure what John's excuse is as watching his video's he's lucky to move in his shed..........although I think there's room under that table he sits at.

The Allbrit planimeter, I know there looks to be a central sort od weight pivot part that is missing but easy to make and I suspect the chrome cylinder/tube with the knurled rim is not part of the planimeter, I have looked on the net and they all seem to be adjustable so the head can slide along the bar, this one looks fixed so can anyone shed any light on this? They are used for working out the area of shapes on charts etc, I did not know this when I bought it but it was only £3 so worth a gamble lol.

Hi Mick, sorry I missed this post earlier.
Here's my planimeter, bought new in 1975 for $150. I think you got a bargain!
The head doesn't normally slide along the sighting bar, though it is held by a setscrew. But I think that would only be used for adjusting the accuracy. There is a test standard included in the kit you can see it tucked into the lower edge of the box. I've never adjusted it.
The pivot bar is fixed in length. You sight throught the glass magnifier, and there is a tiny set of concentric circles for a crosshair. This follows the outline of your drawing, and area is read off on the dials -- there is a coarse dial and a vernier.
I can't get very good pics tonight -- too dark, but if you want I can take better ones tomorrow.
In the box:
As it would be set up for use:
