The proof load would have been 4,5 grammes of NGP M/71 type powder. Was it stamped twice on the same tube or is that some type of odd reflection? I fancy that large K, being either the maker or tube source. The tubeset knitter mechanic CFW was a source for H.A. Lindner.



Me thinks this is Charles Daly Nr. 109 with CFW initials.
