Just looking at the amazing variety of Irish RTR stuff available in recent years, and the tremendous work done by Murphy Models, SSM and others. We can recreate a typical scene just about anywhere on this island from the 1960s onwards, and quite a lot prior to that.
I wonder - just throwing it out there - would there be, in the longer term, a commercial market for some RTR stuff in the late steam era?
This is getting more popular, judging by posts on IRM.
To be commercially viable, it would obviously have to be something very common in the day. If I might suggest priorities based on that, and on wide route availability, there seem to me some obvious contenders:
Locos: J15, 400 class, to join the successful Woolwich. UTA Jeep, GNR "S" class, Bandon tank?
Railcars: Without doubt, an AEC set in UTA, GNR and CIE liveries. Maybe a BUT? If a DART model is viable, maybe, just maybe a GNR artic set as used on the Warrenpoint and Howth lines? And an MPD car.
Coaches: The pre-black and tan scene is crying out for a proper model of a GSWR wooden bogie and a Midland 6 wheeler! And a 6 wheel brake of either provenance. A GNR K15 - brown, blue and cream, UTA green, CIE green, NIR maroon and grey as railcar intermediate, and black'n'tan would all be appropriate for this. A standard NCC third of one of the types at Whitehead?
Wagons: Surely, a "H" van! A CIE brake van or earlier GSWR one, well travelled at the time?
Just a few thoughts. Time to get the mulled wine going....
