The model was introduced in 2000 so if he bought in 2001 he got one of the first. This pair went through changes as the years went by. Castings changed, numbers added, etc. The bridge could easily be worn off as they are over 20 years old. The main things to look for on XX pairs is the shape of the hinges, icon material and colors.Thanks!
Can you tell me a bit more about why (ie why the model doesn't have a lot of the features others do)? Would like to learn some more about them![]()
