I cannot see that being the final fit in a million years. You can see the ridge in the real 419 in my snip of my pic below, and I expect the finished product will be more like that than the sample model linked above.
Having revisited the original unpainted sample pics of the AS tractors I suspect we are going to be spoilt for choice going forward. If you’re an 80s or 90s or most of the 00s you can have a Bachmann 37/4 and for modern 37/4’s you’ve got a choice… similarly with the split box 37/0s. Will the Bachmann new announcements bring anymore joy for us tomorrow I wonder?
Bachmann just need to sort the 40 now 🤭
