The is this device on eBay that looks like its a brass whistle, but it folds into itself and has a cap. I just can't [FONT=&]imagine [/FONT]what it is and the seller doesn't know either. http://www.ebay.com.au/itm/2-x-BRAS...ARE-THEY-FOR-STEAM-I-DONT-KNOW-/281254046529?
I don't recognize those items. Doesn't look like any type of whistle I have ever seen. I doubt that is what is being offered.
Thanks Boxcab, it’s weird but every time I see something strange and made out of brass I immediately think of Steam trains. I must be brain washed. LOL The only other thing I can think of is a fire sprinkler, but it has a screw on cap which would defeat the purpose.
I think Russel that you are exactly correct. I had to Google steam calliope because I had no idea what that was. but after looking at photos I can see that this is probably one.
