I model in n scale where can I find hancock 4700 horns. I model the MN&S and need horns for engines SW1200
Neil_Wallin, while I don’t have an answer to your question, I want to say welcome to the forum. I hope someone can help!
The Hancock 4700 isn’t a horn, it’s an ‘air whistle’. That may be more than a matter of semantics when searching for specific parts.
Apparently no one currently markets one as a separate detail part in N scale, and I have my doubts of the actual print quality if you have an O or even HO 3D file reduced to N scale.
You might be able to fake it convincingly with a small piece of foil formed to the bowl shape and a small piece of monofilament tapered on the end for the whistle.
thanks for letting me know. You gave me some ideas as to what I can do.
