I need some help! I am trying to get a good selection of Alco locos on my layout and have hit a problem. I can't seem to find any examples of the "Alligator" or "Notch Nose" Alcos in the listings on EBay. Can anyone tell me if there are any such HO models, and if so, who produced them? I may be looking under the wrong maker or wrong title, or (I Hope not)there may not be any such models available. Any and all help/ideas are appreciated. Dave
