Protectoscope boxes
 

Hi all,

Does anyone recognise the Prism/Protectoscope box painted white? I got this along with a protectoscope box for an M8/M20 armoured car (the one in OD). I was told that both types were used in M8/M20 armoured cars. The white one is quite a bit bigger than the OD one but the mounting points are the same on both. The OD one is the same as the one I have in my M8. I was curious as to whether the white box had use in other armour.

Can anyone assist?

Thanks.
