I have some of the LifeLike FB-2s as well as a lone FB-1. I have been looking for photos of prototype ALCO FB units equiped with Steam generators and have not been able to find any. Has anyone else out there modified a LifeLike unit to turn it into a "dual-service" unit? Should the FB look like the PB on the top, as far as the generators go, or were they different on the FBs? Also, I am under the impression that equipping an FB-1 with a generator would be correct as some roads ordered them with such (the FA-1s were not long enough for them, though). I have not actually ever read of a road that did so, though...was there one? I am modeling free-lance, so I can fudge a little, but I like to try to stick close to the prototype when it comes to the basics on the locos. Thanks!
