They are mismatched yes. I don't know why. Same maker. Same apparent construction details, down to the 9th degree.
Does anyone know...were these issued, so to speak, as an exact matching pair (a "pair" meaning, made together, at the same time, by the same maker, by the same means, perhaps the same seamstress, and held together by some means, insuring that they made there way to the youth as a "pair?"). Or were they made in the hundreds or thousands, sent to a central point, and grabbed out of a bin, 2 of a time, with little regard for wether they exactly match or not? This to me would be very intriguing to understand. Because actually, if they were produced, adhereing to certain distinct guidelines, by multiple makers, one would never realize that they were mismatched when viewed on two opposite shoulders of a youth or soldier. No one at the time probably was concerned with these items the way collectors analyze things today.
Curious to hear from others.
P.S. I'm away for the weekend.
P.S.S. (I'm calling on my other collecting interests such as U.S. Boy Scouts and Roseville pottery when making some of the observations that I'm asking about. Does that make sense?)
