I have a steam whistle available for sale. It's a replica of a Southern Rwy. 3-chime from MD Whistles. Below is a youtube clip of the whistle on NHRR 40 from last fall.

If you're interested, I'm asking $475 for it, plus shipping. Please feel free to contact me at jmf_rr@yahoo.com with any questions you may have. I'm in New Jersey, and can arrange to meet anyone who's local. Thanks.
