I would agree with that view. But it does seem odd. And while I don’t defend (or criticise) here any of the behaviours of any party - things like Terriergate, Titfieldgate and Shedgate shone a poor light on Hornby for doing their own tooling (or using existing old tooling) to aggressively compete with others (namely Rails, Rapido and Hattons respectively). If (big IF) this is duplication of IP, and of a smaller organisation, that’s another level!
From the EFE releases to date, they all seem to have been either modified existing EFE models (tube stock), ex-Kernow or Kernow acquired ex-DJM. Then there’s the Hymek which I assume was made with Heljan’s involvement.
And also without wanting to drag up unfortunate events of the past, maybe this is also the type of thing that DJM was on about when he appeared at his most paranoid, towards the end of that venture? Of course there may be nothing like that at all!
