Ok, I've looked through several resources but am no closer to the answer. I know that shoulder scales on enlisted Federal Frocks were very uncommon in the field, but they were in the regs. In looking at period pictures, I can find a good number of soldiers both with and without scales. My question is in regards to the scale mountings, were these part of the frock when issued? I have a frock which has the mountings (I also have scales for appropriate times) but when I see photos of men without the scales on I usually do not see the mountings either, is this due to the photo or were they likely not there? How common was it for men to wear frocks with scale mountings without the scales on and when is it appropriate to do so? Am I wrong in wearing my frock without the scales but with the scale mountings in place? If someone could point me to the right place to research this I would be very appreciative.
