There are new FWs made now. SunRace of India makes them as does Shimano. I use both. The Shimano's are better FWs and come with Hyperglide cogs (a mixed blessing if you run friction; they shift too easily. With the derailleur between cogs, the chain can shift back and forth at will, usually as you apply pedal pressure, then again as you back off. The SunRace FWs are heavy, clumsy, clunky shifting but work, shift well with good derailleurs and hold up well.

The Harris/Sheldon Brown website shows the options from both and will deliver quickly. Getting your old selection of teeth will probably not be an option.
