Hancock - Head Chateauroux}2/N.9.6.39, we discussed this matter with Gry.{Shadwell Grylls} and it would appear the change is a bit of a ramp on the part of Prices, and for the time being it is considered you should use the '50' i.e. De Luxe. We will discuss this matter when you come up to the Works. BY/Mtn. | ||
