So I finally got the remover tool - only took about 6 months - and was able to wrench that sucker loose. Turned easily after the initial break-free oomph. Have looked around online some, seems like the only place I can find a Normandy/Maillard/Sachs freewheel (5 speed, 14/17/19/21/24) is Fleabay, which I'd rather avoid. Anyone know of any sources I haven't found? I guess I could always go Shimano, Falcon or some other Asian company - provided the threads match - but this is for a vintage 70's (or maybe 60's) Raleigh Sprite made in England, so I'd really like to keep it as original as possible.
