Appears to be what most refer to as a mainstream sutler row quality kepi. Most of these are mass produced coming out of Pakistan for the collector market. It may look somewhat similar, but in reality is quite far removed from those made during the era. The pattern, material, liner, braiding, buttons, assembly method, and visor arent even close to the quality they should be. Majority of quality reenactors usually avoid these.
I'll second the motion made above for those made by Greg Starbuck... museum quality. I have a host of kepis he has made.
