1970 Morse Diving Equipment US Navy Mark V Helmet


Morse US Navy Mark V - 1970 - #s Matching New Old Stock!

Without a doubt the Mark V is the most popular helmet we handle. While difficult to find authentic examples, these were made in sizeable quantities during World War 2. While many were used up, destroyed or simply lost, a precious few do still exist. Of those few, only a small percentage remain in factory original unused condition. This Mark V made by Morse Diving Equipment is just one of those rare examples!

This beautiful helmet was made in April of 1970. The helmet is serial #'s matching in all 6 locations - the 2 neck rings and 4 brails. During this time Morse was using a lead ID plate. This helmets ID plate is in excellent condition!


Very few Mark V helmets exist from the Vietnam War time period. The primary reason is that the US Navy still had a sizeable inventory of Mark V helmets from World War 2 in their inventory! The few Mark V helmets ordered from Morse were typically sent directly to a new ship that was being outfitted.

This specific helmet was owned by a member of SeaLab III. We purchased the helmet among other items in his collection in 2020. It is likely the helmet was presented to him or simply appropriated after his involvement with SEALAB 3. The helmet will be accompanied by a certificate of authenticity detailing its provenance and SEALAB members name.   

If you are considering a diving helmet for a special gift for someone or yourself, this is one that will instantly impressive everyone plus is a full serial numbers matching investment level example!
