I don't know about that label, but that collar shape is very early - mid 60s, along with the loose bell/swing shape of the jacket. The heighth of Hong Kong tailoring was the 60s through the 80s, with many international companies setting up shop to make use of the talent and the luxurious cosmopolitan hotels where international travelers could stay and purchase from in house boutiques. I have come across many labels that I have not seen more than the once, with reference to Hong Kong. And, then there are the more commonly seen ones that lasted (Gene Shelly, of course) and maintained their reputation. Beading, sequins and tailoring in fine wools and silks are the signature of the 60s Hong Kong era of fashion. This is all to say, it may be difficult to find that exact label, but you can glean lots of knowledge from the garment!
