Hi Guys i think we may be going into the black hole of OOn3 modelling, I do know of a 3D print of 4T by Tom Bell, but again I am not sure what is happening with that. As for a chassis etch I was not aware of one.
So I was wondering if the loco etch and the chassis etch are something that Phil has got done himself, I am not suggesting for one moment that he turns it into a commerical exercise, but that said if you can get say 10 others to buy them from you, you can often get a set done for yourself for free.
I can think of four people not on this list that might be interested.
