C.B. Konig Altona Respirator
This is an early leather smoke rescue mask from the mid to late 19th Century. It was Manufactured in Hamburg Germany. I try not to call everything rare but we have been collecting these for decades and have not seen a 2nd example. I has a bit of a Darth Vador look to it.
This is one of the objects from the Radio Guy collection that inspired Dennis Manarchy's Award winning series and book "METAL"
