I don't think there would be much of a market for thousands of new Mk3s, especially as Silverfox still sells them and they come up on fleabay every month
realistically I think modern rolling stock would make a lot more financial sense and as said before, introduce a whole new breed of modern modeler into the lobby
love them or hate them; Mk4s, IRCs, DARTs etc. is the way to go. We need something operating in 2021 that will still be in IE operation for the next 20 years
what would a 20 something year old pick up in Marks Models getting into the hobby, a model of a 70 year old Park Royal or a current Mk4 that he just traveled in on from Carlow
and been an armchair modeler, that's my two cents lol
