(This list is based on what I have actually seen, more heat stamps might be out there)

First off welcome to TNet, from Florida, and second sorry for the delay in answering your question.
I'll give you some basic history and some information, but pictures will be needed to fill in the gaps.
For starters the M1917 was a US made copy of the British made helmet. The British made the Mk1, the US used British made Mk1s, before getting everything together to make their own copy called the M1917. Between 1932 and 1936 the US modified some British made Mk1s and US made M1917s with a new liner and chin strap, some sources refer to these as M1917As. Then the US made new shells with the new liner and chin strap and these helmets were referred to as the M1917A1.
Now as to your helmet, the HV 66 marking is broken down as follows.
The "H" indicates that the helmet was made by Hutton and Sons Ltd they produced helmets starting in 1915.
The "V" is for the steel supplier, Vickers Ltd they began supplying steel in 1916.
The "66" is the heat treating lot number of the steel used to make the helmet.
So a Hutton and Sons made helmet, made with steel supplied by Vickers Ltd. Your helmet is a WWI era British made helmet.
Beyond that without seeing pictures of it, that is as far as I can go with my information and identification. Post some pictures of the helmet, the liner, the chin strap, chin strap bale rivets, and I can tell you more. At the least you have a WWI made Mk1, that could have been used by the British or Americans. It's possible that it was modified by the US before making the M1971A1 helmet, or not and could just be a British helmet. This is why pictures are needed.
sorry if the pictures are weird or if i did anything g wrong i?m getting new to this platform.
Pictures uploaded just fine, no problems there.
So to make it simple you have a British made Mk1 "Brodie" helmet, used by the United States during WWI and called the M1917 by the US. Prior to WWII (1932-1936) the US upgraded these helmets with a new liner and chin strap assembly and re-designated it the M1917A1 "Kelly" helmet.
As stated prior you helmet was made Hutton and Sons with steel supplied by Vickers Ltd.
