We won't get into the details of how it happened
but one of our Kahlenberg Horns fell off. Amazingly enough it appears to be held onto the bracket by this threaded nipple to supply the air. Any ideas on where to find one of these? Or what to search for? Searching airhorn nipple on google, while entertaining, didn't provide much help.
Also while we're at it any tips on cleaning these up while I got them off?
