This is a very early Schrader sponge helmet.  It most like pre dates 1900 and was later updated with communication fittings as you can see in the photos.  The helmet is well used and has a fantastic patina.  This helmet is a true collectors gem and should not be confused with the fakes out there on the market from India and the Orient.  We will consider trades on this item for vintage scuba items to augment The Scuba Museum's collection.  The museum is currently looking for a TOA Lung double hose regulator.

Price $1500.00 plus freight.
