| X.4260 Extract from R7/M30.12.21 X.4219 (14) FRAMES. X.4260. With regard to the pressing of the side channels, I am quite agreeable to dealing with Thomsons' or anybody else that suits us. I suggested frames should be .156 thick and made from the steel Thomsons' have in stock, hot pressed if desired. For sports or chassis carrying light bodies the frames could be perforated.
