If you ever wanted a Classic Watts' Top, you still can. I have exactly six 5" left and then they are gone. No 4 or 6 inch left. Prices are on the wattstops.com web sight. Shipping has gone up so add $10 to the shipping amount unless international then contact me.
I made my first Watts' Top in 1993. It was an enjoyable hobby. I have tops in at least 12 countries that I can recall at the moment. It has been great to see others making quality tops, several that I had the joy of coaching a bit.
