DJ, many thanks for your comment, gratefully received, just to confirm, the middle one and small one WW2? I have 7 members of the family serving in the Artillery from 1860 to 1958, i appreciate it's a wide field! I'm not sure what a cascabel shape is, i have been concentrating on the dots of the carriage and what must be handles on the same carriage. Do you know of any work/reference that may help, is it your belief these are all Canadian? and if so why? comments appreciated Mark
