Replacement for Maillard Freewheel for Raleigh Record?
 
Hi all - I'm rehabbing a Triumph branded Raleigh Record. I thought I was just about done, but it would seem that the smallest cog on the freewheel is toast - besides it looking rather worn, the chain skips like crazy when force is applied.

The freewheel is a Maillard, the hub is Sturmey Archer.

I read on Sheldon Brown's site (Traditional Thread-on Freewheels) that different freewheels are threaded differently. However, I don't know if mine is French (Maillard) or English (Sturmey Archer) threaded.

Will regular run-of-the-mill off-the-shelf freewheels thread onto my hub ok?

Yes, though French threaded freewheels might be hard to come by. I would bet that it is English (ISO - 1.370" x 24 tpi) threading. If you remove the Maillard freewheel, either it or the hub may be marked for threading. Sometimes they used a ring or stripe on the hub to indicate (can't remember the details). Since this is on an English bike (Raleigh), I'm not aware of Raleigh ever using French threading.

I don't think Sturmey-Archer ever offered a metric thread hub. Maillard freewheels were available in either metric or English thread. Chances are yours is English. You can test this by threading a known, English thread bottom bracket lockring onto the hub. If you can thread it on without binding, thre hub is English thread. A metric thread hub will only allow the lockring to thread on for a partial turn.

Some freewheel bodies are marked with the thread type:
