After a bit more poking around it appears that Temsco may have sold the STC to a company called Trinity Aviation Group in British Columbia. As far as I know the Temsco prototype is the only one they built up and that was about 8 or 10 years ago. The Trinity web site is a bit strange as there is not much information on it and you can't find out too much about the company ( at least I haven't been able to). As with many older helicopter platforms, when aftermarket things have been getting made for years, there are many players involved. Some are well known and some are not. Some are producing and some are no longer. Stcs get bought and sold.
