I want a set out of the last order to be delivered in black and yellow.
No worries. I tried searching Athearn but for some reason they have removed the older runs of Genesis F7's from their website. I'd think if they ran the back and gold phase I F7's, the detail changes were fairly minor between the 55xx series and the 56xx series, the 56xx series being the last delivered in black and gold IIRC, the 57xx coming from the factory in grande gold/silver. If you could find any of those, you could renumber them. The detail differences mainly had to do with the engineer doors having square edges or round edges, water feed doors, headlight bulb differnces etc.
