Hello everybody, I would appreciate a clarification on two issues related to duties and trades First question: does anybody know the meaning of "check" in the following reference? from Trux's forum TELEGRAPH OPERATING SECTION War Establishment III/25A/2. December 1943 "3 X assistant tradesman for duty as checks" The second question is related to whether these "checks" were tradesmen or not. I am asking because even though they are called "assistant tradesmen" in the telegraph operating section, they are classified as non-tradesmen in another WE (Canadian) I have seen. For example, from Operating Section (CDN III/29G) - RCSigs.ca the CDN III/29G/1 - effective 9 June 1942 mentions under the "non-tradesmen" group 1 batman 8 checks 2 drivers IC. Thank you p.s. I noticed in the Canadian WE that even drivers IC are classified as non-tradesmen. I thought that any type of driver (including a driver IC) would be considered a tradesman.
