'69-70 model 10-5
The SN is dated but i have a different question. inside the arm where the cylinder swings out is a different set of numbers as well as 2 letters( X N) that look hand punched since they are off centered.
Both of the SNs are 92 xxx but they are different so i supposed the cylinder was replaced at one time. but whats with the xn? any guesses?
