Wilson Bernhard Langer irons HELP!

I still use a set of Wilson Bernhard Langer golf clubs, the set includes 3 iron through to sand iron and a 5 wood and a 3 wood I purchased them in England in the 1980's for around 220 pounds sterling. I use a balanced face putter purchased at the same time made by Wilson and a large headed titanium driver not made by Wilson I have played on average twice week in Scotland, England, France, Germany and now New Zealand for 30 years. I look after my clubs and clean them after every game. I have re-griped them four times, They still look like new with a fine bright shine on the woods. I would not change them ever, as they have served me very well. Is that any help?
