Well Ive made a decision last night with a quick but significant purchase. My first G3 loco definitely is going to be a Neilson 12" with Ogee tank. And for simplicity now, Im using the technically incorrect but justifiable Slaters 3'6" wheels. As I want an industrial example rather than GER owned, I can just say the GER sold one off after the first rebuild for whatever reason. Rule 1 and all that. And later-on, I can always commission those lovely Mark Wood wheels if I change my mind. Ive also done a lot of 3D cad work for the superstructure as its all going to be 3D printed in WSF material. Itll be rough, but the size should make it easy to fill and smooth out. Just have to work out how to drop the cost of the parts from almost $200 to something a little more justifiable. The Ogee tank alone is almost $75. Hopefully I can sprue some of the bigger parts together to try to save on machine space. Unfortunately, my progress on the L&Y D1 and D21 has been halted due to the wood order taking longer than I was quoted. But hopefully Ill soon have something to report.
