Suntour Alpha freewheels (with just simple additional bevels canted along two axes on every cog) are nearly in the same performance league as Uniglide when it comes to good friction shifting. I believe that the bevels were designed to simulate Shimano's UG twisted teeth but without infringing their patents.
I modified the teeth on my 1979 Fuji Pro's Ultra-7 freewheel to include the Alpha cog bevels, and now it shifts with the best of them even under some amount of pedaling load!
No, Sante was 5000.
All the part numbers are in the 5000 range.
