Fyr-Fyter Penetrator push button siren

Recently picked this up and it works great! The seller even included the original manual for it which I have scanned in and included as a PDF file here. It includes the full internal schematics (@MtnMan probably already has it though since he is THE siren guru). I recently got back in to siren amps, so I have been slowly building that aspect of the collection up with some uncommon finds.

1960s vintage electronic sirens are good to collect because they have lower pitched wail and yelp tones than the sirens we hear nowadays.
