I seem to have a pair of Maillard 700 track hubs. Atleast the rear hub is threaded separately for a cog and lockring and seems to do the job (haven't used them yet). I've never heard of Maillard 700 track hubs before and I haven't found anything by searching. Is this the real thing or what?

Took some pics now but they really suck, sorry for that. The rear hub is disassembled for cleaning. Yeah and the blue spokes are god awful - not my fault. The wheels came with a track bike I bought a while ago.
