Maillard freewheel - French threaded?
Curious if anyone can tell whether this would be French threaded or not? It has the large splines, is attached to a Normandy high flange hub and the rims are 700c with a Raleigh sticker.

the hub will be a clue
if there is a groove on the hub shell inboard of the gear block and outboard of the hub flange on the drive side the hub is BSC threaded
if there is no groove the hub is metric threaded
a metric threaded gear block will not thread on to a BSC threaded hub as the BSC pitch diameter is greater than the metric
example in photo is BSC

N.B. you want the Bicycle Research CT-3 or VAR-405 tool to remove that freewheel from the hub.

addendum(b) -
duke,
forgot to mention above that there is no possibility of Italian thread in this case to be concerned about as Etablissements Maillard made no hubs or gear blocks using it

I ordered mine from Ebay seller in Greece. That was Thanksgiving weekend. Seller shipped right away. It just hit customs in NY last night. Now comes the scary part...... The USPS distribution center in Hazelwood, Mo. Known in the USPS as "the Blackhole"........ If it gets past them I'm home free.
