which models?
original ones ( plain uncoated carbon ( grey) or one of the newer models
i have 2 of the original ones 20/40 and 20/50, the 20/40 has been rebuilt by alba rods ( stan massey ) and the 20/50 has also been rerung with decent sic rings as opposed to the cheapies it cam with
any use? as there is minimal difference in the 50 n 60
