RARE Pre WW2 US Navy Submarine SONAR Sound Head Projector ASDIC
Up for sale is one Pre World War 2 US Navy Submarine SONAR Sound Head Projector ASDIC. I don’t have much information on this unit but it is definitely a RARE FIND. It is either a Magnetostriction or Piezo Transducer based on my research but could also be a Fessenden Oscillator. The unit was connected to an oscilloscope and you can see oscillations when tapping on the projector head. I did google the part numbers on the unit shown in the pictures but wasn’t able to find any information. The whole assembly is made of mostly brass and possibly nickel or stainless steel. There is some sort of rubber material on the back of the projector head. The unit measures around 24 inches long and has a long two conductor cable attached. The SONAR head comes in a rugged storage case with no part numbers or markings. The numbers on the Sound Head are as follows.. ESO – 671351 (In Brass Casting). 35 ONR5 (Hand Painted). USN 62190 – 000675 (Stamped in Brass). 5B 20 (Stamped in Brass). BARGE CR C G 6B (Stamped in Brass). This SONAR Head is a very unique piece of history and belongs in a museum. Please feel free to contact me if you have any questions. Thanks for looking and GOOD LUCK!
