Assistance Identifying and Authenticating Uniform

[ATJcostumer]

Hello ... trying to get some assistance in identifying  whether this uniform coat is authentic, and if so, an authentic what?  ... or is it a vintage and truly lovely costume piece?   In either case it is really quite old and very handsome.  Please ask questions ... if there is anything can tell you that would help, I surely will.  There is a lot of hand work in the lining ... but the outer shell seems to be machine stitched ... 

Thanks in advance,

Rick
