As long as you understand that the "V" is the Roman numeral for "five" and continue to call it a "Mark Five", not a "Mark 'Vee'" when calling about one on the phone.:wink:
 
One easy way to tell an original from a replica is to look inside the hat. Real ones have air channels to direct the incoming air over the ports to keep them clear. Repos don't have those. I have several hats that I picked up years ago. I couldn't afford one now. Prices have just gone through the roof.
 
A real hat will set you back $3500 to 6000+ with the ones from the 1800's going above $10,000 now.

Here is one of the best sources for information: Historical Diving Society | Other web links

If you have the coin and are serious about buying a hat they can help hook you up with a seller and also give you some pointers about telling a repro from a real hat.

This site can tell you some of the things a real hat will have and a repro most likely will not. But beware that there are now some high quality repros coming out of India that are hard to tell from a real hat: US Navy Mark V diving helmet

Another way is to order a new hat from DESCO or Morse, they still have all of the tooling and you will get a "real" hat from the manufacturer with a serial number but it will be a new hat and not sell for as much as an older one. Expect to have to put a hefty 50-75% down before they will make it. Morse Diving, Inc.

Finaly, here is the Historical Diving God, Leon Lyons web site: Helmets of the Deep - Leon Lyons maritime collectibles - St. Augustine, Florida
If you ask nice you may be able to arrange a visit to his museum collection. Drop off your boyfriend in the morning, go shopping, have lunch, and pick him up at the end of the day
 
" Early diving helmets did not have nonreturn valves. This meant that if a hose was severed, the high-pressure air surrounding the diver rapidly and with incredible force evacuated the helmet. At even a modest depth, the tremendous negative pressure created by the escaping air caused an extreme and often life-threatening squeeze on the diver.
In extreme cases, the negative pressure caused by a severed air hose could actually suck flesh and soft tissues up into the pipe and much of the diver’s body into the helmet. Stories abound, in fact, among old-time commercial divers, where so much of a diver was sucked into his helmet that it was buried in place of a coffin. (And you thought an ear squeeze was painful.)"

I am looking for a Mark V but never seem to be able to get the deal I want for one. One thing for sure is that they don't seem to lose value so I would imagine you can look at it like an investment.

There are some other helmets that are not as pricey on the market. I recently picked up a Morse Mark 12. While it does not have the cool factor of the Mark V, it is pretty fun to dive. I traded about 400 bucks worth of dive gear for it so it was a bargain. I could sell it for much more. Much of getting a helmet at the right place is being at the right place at the right time with ready cash.
Good luck on your quest. You are a good girlfriend !

These are currently on display in my office. I do have the breast plate for the Mark V, just not on the helmet at the moment. They are original, as I work in a museum.

The colored ones are Swindell hats from I would say the 70's.
