Or a Sach/Maillard Aris. Those are a piece of cake by comparison,

Sutherlin's (1980 edition) makes some vague reference to the fact that some FWs have one or two large cogs that screw on from the back of the FW, while the rest screw on from the front. It's been a while since I did this, but I seem to recall that this is the case with the Regina Oro. Correct? Is it one or two cogs that thread on from the back? Do the cogs thread on counterclockwise on the back and clockwise on the front as would seem logical? What is the general experience as to the difficulty of removing the cogs using a pair of chain whips? Any special tricks to this?"
The venerable Cyclo-Pedia catalog had an illustration of the Regina Oro 5 and 6 speed freewheels:
and it indicates that the two large cogs thread on. Presumably with left hand threads, since they butt up against a flange separating the 2nd cog from the 3rd? Seems like a royal pain, regardless. Is this where a freewheel vise comes in handy? It sure makes me appreciate how easily the SunTour Winner Pro's come apart. :-)
