Great work on the piper. However this is a very difficult uniform to find. The picture that you use for the piper confuses me. He seems to be more of a civilian or clan piper rather than a regimental piper. Yet on the pipes are the colours with what seems to be a regimental insignia, this insignia is the only regimental sign I can find on his uniform.
The single breasted doublet was not seen until 1856 where the year before they where double breasted. Yet I have found images of a piper of the 93rd and other regiments with a single breasted doublet in 1854. I assume the source I use is only referring to enlisted men, NCO's and officers but it is something worth mentioning. I can't really provide much help on pipers past 1852 so most, if not all my points here are due to a lack of information on pipers themselves rather than any sources.
The only thing I can say for certain about the uniform is the full fly plaid. The plaid is supposed to be warn around the left shoulder and come just above the gaiters. It should also hold a regimental brooch slightly to the right of the centre of the shoulder and just underneath the shoulder strap.
I shall ask my reenactments quartermaster if he knows anything about the uniform for pipes during the Crimean war and if he does I shall try my best to describe what he says. Great job on the mod thus far, I cannie wait to see it when it is realised.
This looks bloody amazing laddie, nice work. I apologise I could not have been much help when it came to individual regiments but still I hope my information was of some use.
Just a wee nitpick when it comes to feather bonnets. The small section just under the checkered section of the hat itself should be black rather than blue. Also I think you removed it but it is hard to tell in the NW the Kilmarnock has some green in the checkered section which should be white. The hackle should also be about an inch for so above the bonnet.
