I've found a cool website where you can create and download FREE ringtones. Registration is free too. I've created a few of a SP 6 chime whistle. I downloaded them onto my phone and saved them as a ringtone. If you have sound recordings of horns and whistles, please upload them onto this site. Be sure to give them a good yet simple title (ex. Nathan M-5, Union Pacific 3 chime, Leslie S5T, etc.) so we can find them easily. I think this is a great way to share rare sounds with everyone else out there. Check it out...
If you want, you can email some to me and I can upload them too. I will make sure that you get the credit for their origin.
