Ex amtrak k5la

Hi all, I just picked up an ex Amtrak k5la in gray with snow cones and all. I was wondering how old is the horn? The serial number is 137XX if anybody has an idea please do tell.

Cool. Got any pics? Not sure about the age - the best place to find that out would be on the Horn and Whistle board but I think it’s broken at the moment.

Here are some pictures and of my collection too.

I see in your Gallery of your collection that you have a Nathan P3 with a high mount manifold Would you be kind enough to send me some photos of that manifold with the dimensions? I can explain what I need if you are interested in helping our project.
