With the size of the ties in the back, I don't think there is any question. I've never seen an officers' quality balmoral with an adjustable headband. (They bought them private purchase, meaning they were tailored specifically for their head - so they didn't have a requirement for "adjustable" headgear.) I don't claim to be an expert, however. The photos seem to show fairly rough serge as well.
The analysis so far in the thread seems consistent with what I think I know about this type of headdress.
