This is my problem,I don't have the slightest idea who's behind the "possible" development of these couplers. All I know is the man who drew the design for them & he isn't sharing any knowledge on ownership. At 1 time in the early development of these couplers,the "3D man," was developing draft gear for Atlas cars that would allow these couplers to drop right in place. That would be a great idea I think then sales could be made to Atlas and likely to MTH&Lionel. I'd throw in with this idea.
I think you mean I can expect to see these couplers when Hades sees it's 1st snow storm. LOL
