Most helpful indeed as was the "Forces" description of Artillery units and their ordinance. Particularly liked the Martingale badge with leather backing as it puts item into scale perspective. Seeing the hat badge and martingale badge side by side I was at quandary as one was either very large or other was relatively small. American Cavalry martingale 'hearts' are almost 3" wide. Canadian 'NWMP' martingale badge,(Striking with Buffalo[bison] head in relief) is much smaller, closer to this ZARP martingale badge. Thanks again for all these related posts. As doing this impression is in its 'Early Beginings' stage here in USA we sincerely appreciate this accurate assistance.
