Hey Glock. Great Idea and work on the whistle. Thanks for sharing and the great photos. Years ago I bought a knock off of the AITOR JUNGLE KING. Some of the gadgets were ok, butthe the tiny steel whistle was very good. Takes up little space in an Altoids tin and is very shrill but not as loud as a FOX 40 of cocourse. I think I'll look for one of those buckles and cut it down for the ultra light kit I'v been working on. Thanks again.
