I think if anyone can come up with a prototypical Irish 20' chassis, you are onto a winner as this forms the basis for many other Irish wagons.
Weshty, just curious if you will be releasing the 47' flat anytime soon, and if you will consider doing a brass etch for the fertiliser wagon doors, seen as you have the 42' flat wagon nearly ready for release. If the doors were available as an add non, one could construct a fertiliser wagon with a few bits of plastic, as they were built on a 42' flat wagon chassis, if I am not mistaken? Thanks.
