Stripping and buffing would tell you more.The pits look like they might be too deep to just plate.You could settle for plated pits,(which is what I would do) or you could opt to spend the money for the plater to copper plate,buff down,and do it again and again until the pits are filled.The $100.dollar bills add up fast doing that.Then again,you might get the frame stripped and buffed to find the pits are not bad at all.Pictures can be deceiving.If you haven't had any chrome work done lately,be prepared.Shock may not describe what you will find out.
