Mart Chorne Custom Fit golf irons: 3 - 4 - 5 - 6 - 8 - 9- -W (missing the 7 iron). True Temper "Dynamic" Steel Shafts with Velvet Cord Golf Pride Victory Grips.
I have researched these clubs and have determined the possible manufacturer and distributor/retailer. It appears that in the 1980's, Robert Chorne (patient holding golf club head designer) and his company, Nassau Golf in NY, manufactured these clubs to be sold exclusively by a Northwest US retailer as a private lable iron set.
These clubs have been used and are in fair shape.
