In 1998 Scotty introduced The Art of Putting model. The Oil Can finish which with it’s varying oily rainbow hues in my opinion is the nicest finish Cameron has done on any OTR putter . According to the experts on the Cameron Collector site, the finish was actually done by Black Oxide Services, located just down the road from Scottie’s shop. The Cameron Custom Shop no longer offers the oil can finish for a restoration. This putter has the more desirable “oval track” back cavity and is in pristine mint condition with the grip still in plastic.
