I own a cashmere coat in my personal closet with a similar lining and it has a Hong Kong tailors' label. I believe it was Peter Pan tailors, and the owner's name is embroidered in it. It is sort of a Is it Lipstick Red?/Is it Fuschia? color and the lining definitely is the odd choice of reddish orange in comparison. I am not saying yours is from the same tailor - there are many - but the all of the stitching in the lining of mine is very similar to yours. S lot of these tailors copied whatever the customer wanted pretty much. Based on the label of mine, bracelet length sleeves, et al, I dated mine to the 60s. The style of the lapels of mine differs quite a bit from yours. I always love how well made they are. I bought mine for a steal because the color was very hard to photograph (it glowed like a beacon), so I took a gamble that the color would be better than the pics. It was. Anyway, I would guess it is similar in origin to mine, as Pinkcole suggests, rather than a "name" designer form Europe or the US.
