Alert whistlers

Alert whistlers was created by Peter Kirk
Whilst going through a stack of documents, currently about a foot high, I found a reference in a USAAF file relating to Intruder warning systems (IRIS#228646). Within that was the warning to be sounded for an "Alert" which was by running an exhaust whistler on airfield defence jeeps. I have not heard of these before.

I can only imagine this is similar to the prank you used to play on teachers cars by pushing one into the exhaust pipe so that it made a high pitched whistle. These were somtimes difficult to retreive though. Better to use an unbranded profalactic and a jubilee clip though. Every home had a supply of different sized jubilee clips when I was a kid and I still do!

Still available as a novelty item:

They tend to be called hose clips today and for a good reason. I recently bought a box of assorted 'hose clips' from a well known German discount store for a paltry sum. I've used a few and have found that you just about get it tight enough and the thread strips. Would not have happened with a genuine Jubilee (British patent) clip.

Wonder if they used 'hose clips or Jubilee clips on their V2 rocket engines?
Plan A is always more effective when the problem you are working on understands that Plan B will involve the use of dynamite :twisted:

Funnily enough, working with a German fella he teaches me all sorts of weird words.

Apologies to Mod for being off topic with this, but I will stop here.

German can be a good source of amusement. Schadenfreude comes to mind.

When I worked for a German company we had three interesting co-workers. Gerti Rottenfusser, Hans-Peter Shite, and Wilhelm Wonka who always picked up his phone and shouted "wonka" down the handset. An endless source of fun on a miserable wet day.
