I downloaded the picture and then blew it up, there are definitely different types of carbines and long guns, what appears to be bayonets are actually slings on the long guns making it look as if there was a bayonet with a handle. What a nightmare it must have been to supply this unit with ammunition, wonder it they had their own molds? I thought I could identify a Burnside, Maynard and a Smith, but as it was expanded it started to lose resolution. At least two in the ranks also have Cav sabers. The bottle or bugle, is not discernable even blown up, but I can't imagine it being a bottle since this is a fairly serious picture, but who knows.
