40 m/m BD{Mr Berend} Type Gun.

Pedestal type Naval Mounting.

Item 5. Adjusting Washers for Trunnion Pins. CR.{Mr Cra???ster / Mr Chichester}125/9.

As the position regarding the assembly of future guns to their mountings, is a little obscure, it is intended that the Experimental Dept., shall produce adjusting washers as required for their respective cradles.

I understand some criticism was made regarding the finish of the LMS washers, and in view of this I think until such time that BUSM and LMS are working together, such an arrangement will be most expedient for the delivery of these guns.
