Ev{Ivan Evernden - coachwork}/JD.{J. Draper - Frames}6/SW.10.1.41. MYTH. FRAME. We attach to Rm{William Robotham - Chief Engineer}/HH's copy the original of PL.441 Frame Front Gussets. The above scheme shows the front end of the frame to the cross feet, stiffened by boxing the side channels. The gussets fit inside the channel, and they are spot welded and arc welded together to obtain the maximum stiffness. On later schemes the fixing of the front pan, front bumper, front roll rod, dashboard mounting, pedals and the holes for spot welding, will be dealt with. Ev{Ivan Evernden - coachwork}/JD.{J.
