will a Shimano 6-speed freewheel fit on Maillard hub?
Dave Griscom
has a Maillard rear hub and a worn 6-speed freewheel of unknown origin. Can
I fit a Shimano freewheel on this? Thanks

Maybe.
Without knowing the origin of the wheel or whether the hub is threaded
standard or metric, you'll have to remove the freehweel, clean of the back
side and see if there is a notation. Classic freewheels are unmarked when
they are threaded country-of-manufacture. That is to say an unmarked Regina
will be Italian, an unmarked Maillard will be French, etc.
The mark you're looking for is either an "A" (anglaise), an "I" (italienne),
sometimes just an X or an O. Later models from Maillard are clearly
labelled "1.370"x24tpi" which would be great to find.
You may swap British and Italian freewheels with impunity but the larger
French threaded hubs cannot accept modern ISO British freewheels.

setup a bit more carefully. The only markings I could find on the hub were
"Maillard Made in France" and "45 84" (perhaps a manufacture date?).
After scraping the rust off the freewheel, I found "Suntour Made in Japan"
and the marking "NWN". This setup is on a Raleigh Record perhaps early
1980's. Its an inexpensive bike but serves well as a trainer. Does that
help narrow it down? Thanks again.

Close but no cigar, Ted- the Helicomatic freewheel mechanism was
seperate from the hub (like a "conventional" freewheel), but the hub
and freewheel had a helical interface. The Helicomatic freewheel
mechanism and cogs were an integral unit. I think there's a couple in
the junk bin at Citybikes if you want to go look.
Back to the original question- as others have said, unless you have a
very rare French-threaded hub, you will have no problem fitting a
Shimano freewheel to it.

Yes perfectly.
By 1984 there weren't any metric freehweels, at least not on USA model
bicycles. And your Suntour freewheel, as suppied on a 1984 Raleigh, is
standard BSC thread.
Suntour freewheels, BTW, when metric are clearly marked on the front ( much
handier than stamping the back!)

Jeff is right, and I (Ted) was wrong.
I should know better, having worn out two Helicomatics on my favorite
touring bike. Thanks for the correction.
