I am not sure that the "symbols" below the cockade are numbers. I think they could be Cyrillic letters. "B" (pronounced like "v") and the letter which has the sound of "P" but which I do not know how to illustrate here. It looks a bit like two capital "I"s close together. An abbreviation for something - like R.A.M.C., R.A.S.C., etc.? It could also possibly be the letter which looks like an "N" written backwards which has a sound of "ee".
