I would say pre'77ish as went rounded after that Has it re rings? These changed around 77.

Pictures would help ..

its a chrome set, any idea what they would go for? its a five piece set in decent condition, for some reason it wont let me upload pics from my phone.

Thanks

Without pictures its unlikely anyone's going to venture a guess, certainly not an accurate one. No size info. And your assessment of their condition may differ significantly from ours.

Is it a chrome over wood kit or a stainless kit?

Are there reinforcement rings along the bearing edges?
