Kaiman Polish hose loop assembly

Ok, these may be common in Poland, but I doubt that even. That being said, we have only one to sell. This is a very nice example of a Kaiman 2 hose assembly. You can see from the picture they were made with no regard for expense. The mouthpiece has stainless knurled nuts to screw the mouthpiece into position. The construction rivals that of even modern rebreather mouthpiece in my opinion. The hoses are one inch on both ends, and are useable in my opinion. The loop is most likely used but it could be NOS with dive shoppe storage dust.
