| Coil Springs. (Extract from Rm.{William Robotham - Chief Engineer}1/JMS.13.7.40) There have been one or two problems with gun springs over here, and I have asked them to pass the problems over to you so that you can take them up with Zimmerlei. I still think that Barnes, Raymond & Gibson know more about coil springs than any one in this country. | ||
