One of the most impressive and rarely seen diving helmet designs of the 19th Century is the 5-bolt pattern. This beautiful and never used example was made by the A. Schrader Diving Equipment Company when it was located in Bowie, Maryland from 1999 to 2018. The helmet is complete in every regard including a brand-new Schrader non-return valve. Over the years since it was made the copper and brass have started to develop a slight patina. This could be allowed to progress or with simple metal polish it could be brought back to a brilliant shine. This is a 100% authentic helmet and very impressive visually. Five bolt helmets are inherently heavier than other models due to the thick sold brass neck rings where the five bolts seal the bonnet and breastplate together. Wonderful helmet for display or with proper testing and certification, to use! Helmet will be accompanied by a numbered certificate of authenticity detailing its history. A matching serial numbered hologram decal on the inside of the helmet from Nations Attic will be applied as well to preserve the helmets history and authenticity. The display stand shown in the photos is not included. The option to purchase one after the auction will be provided.
