Just a guess about service, but by the time M4A1(76)HVSS would have been sent for service overseas, many M4(76)E8 were having extra armour plate added, by way of pieces of armour salvaged from other damaged / destroyed M4.
There were examples of the entire glacis plate of an knocked out M4 being welded on, and used the fittings of that glacis plate for things like lights etc. Extra plate being added to the hull sides as well. It would have been much harder to effectively fit that applique armour to the curved surfaces of the M4A1.
Of course the British used the hybrid hull VVSS for a number of 1C Hybrid Fireflies (yes I know, they were not called Fireflies at the time).
Israel later used M4A1 with HVSS as the basis of some of its Isherman variants,
so it could be assumed that they were from excess war stocks exported from the USA rather than from anything that had been sent to Europe in 1945.
Many Israeli Shermans came from France, so it can be assumed they were late model M4A1(76)E8 supplied to France by the US under MDAP, and many M4A1 were supplied to other allies / friendlies post war, many of which would have been HVSS. The one in the photograph above may have been not a WW2 service vehicle but a post war vehicle supplied to France that someone thought would have been a good memorial.
