| X7535P JD.{J. Draper - Frames}106 25.11.30. X.4642P. X.7535P. P & R MOULDED VVENT PLUG. I note in Mr. Pritchett's letter CGFP/GL.{G. Linnett} of the 22nd inst. he is putting in hand the new type moulded vent plug for the 40/50 3-RRN11 battery. He does not mention he is doing this on the 20/25 6-TBD7E battery. I think this item should be standard on both batteries. GJ. | ||
