Draper - Frames}6/SW.13.5.41. 40 m/m Gun in Beaufighter. Please find attached blueprints of the following schemes :- QPL.185 Arrgt. of Blast Tubes - 40 m/m Gun in Beaufighter QPL.186 Revised Installation of 40 m/m Gun in Beaufighter QPL.187 Section thro' Beaufighter Fuselage at Gun Magazine QPL.188 Section thro' Beaufighter Fuselage at Front End of Gun Cradle. QS.258 Mock-up for Ejection Chute - 40 m/m Type B.F. QS.260 Scheme for Rear Mounting and Adjustment. QS.263 Cradle Attachment Rear Mounting. QS.264 Front Mounting R.R. 40 m/m Gun in Bristol Beaufighter. QS.270 Plan View of Rear Mounting Adjustment Unit. The above schemes which have either been produced by Ve's Dept., or the Clan Design, complete the work necessary to get the guns in the Hucknall & Duxford planes. We. is contacting Bristols, to get them to do their share in altering the planes. We expect them to supply panels to fit the nose of the plane and take our blast tubes. They will also provide the necessary space in the hull of the plane suitable armoured to protect the plane skin from damage by empty shell cases. The hole in the keel plates for the ejected shell cases to pass through, will also have to be agreed to by their stress people. The crossmember supporting the rear mounting, will also require modifying to suit our requirements. Dor.{Mr Dorey} hopes we can get the guns in the Hucknall plane, by the end of next week as the plane will then be ready for further engine tests. Ev{Ivan Evernden - coachwork}/JD.{J.
