Thats some very impressive modelling there Tom. They are certainly going to make an impact once on a layout.
I wonder, given their size, have you considered re-gauging them upto On3, which I understand is not too difficult with the Bachmann mechanisms. Though they would still be at the bigger end for 18" gauge, the wider gauge would look more in proportion.
I hope this is going to come across right and that you wont take it the wrong way. I know in the past that you have questioned wether labelling your stuff as Gn15 is correct and have considered using a different term. Well, with these, I can see that the label doesnt fit and you are probably not doing yourself any favours by referring to them as such, so it could be a good idea to use something else to describe them. What that would be I'm not sure, I think you considered Hn18 before which would probably be more fitting and would show a seperation from Gn15 in terms of size. You could start a whole new trend, it wasnt that long ago that Gn15 started in that way.
I had better add, I dont mean that there is no place for you here, as there certainly is and there is plenty of room under the umbrella of this community for all sorts of different approaches. I just think it would be a benefit to you to show that your stuff is built differently than the tiny electric mice that some of us play with
. I was going to send this privately and maybe I should have, but it may prove to be the opening for an interesting discussion on the topic, again highlighting that your approach is different from that normally thought of as Gn15. I can assure you, there is no offence meant here, I respect your work too much for that to have been my intention. Better shut up now before I dig myself a bigger hole
