That s true...the French only took enough to cover the advance they had made,as Remington wernt in a position to return the money......the delaware factory was new,and it seems most of the workers there had issues,and had been fired from other plants.Anyhoo,there was continued industrial trouble there,hardly surprising when the European war pushed up food prices massively...............However ,as to the heat treating...Ive seen no evidence of this in the few Ive examined,that have been fired with the MG ammo.......It may have been an excuse.from what Ive heard ,the guns were out of spec................now when Remington signed up for M17 production,the first thing they did was ask for a relaxation in tolerances by .002"...(004 total)....In WW2 ,Remington also asked for a relaxation in tolerances on the Springfield contract by the same........This is the reason Springfield Arsenal were opposed to Rem and Win making Springfields in WW1
