I have some Winchester 6.5X55 brass that I think has been reformed into 7.5X54 French MAS. Based on they fit a 7.5 French MAS RCBS trim die and a check in Cartridges of the World 7.5X54 case dimensions. 2.1" length, 1.69" base to shoulder (best i could measure with a set of dial calipers) .330 outside neck diameter, and .304 inside diameter.
I do not see any evidence of an expansion ring at the base although the insides are not new brass shiny. If you look closely, they have a small "doughnut" at the base of the neck. They are too short to be reformed back into 6.5X55 so that isnt an option.
$25/100 includes shipping in a small flat rate box. Or, $55/240 shipped in a med flat rate box.
Look at the pictures, hope you can use em or repurpose them into the newest wildcat something.
