I think I know what you're looking for, but it doesn't exist.
Part of the problem is that back in the day Ping had nearly 100 different putter designs. Karsten Solheim came up with design ideas , making molds, and offering the putter. Since Ping did their own production the company produced the putters only when retailers placed orders, so Ping did not run the risk of too much inventory. The only cost to Ping was in making a new mold, and Karsten was willing to go ahead and make a new mold if he thought the new design made sense. This is how Ping came to offer lots of putter models. There were some wild designs.
Pings website has a "classic putter" section which still has photos of lots of the old designs, but not any written description about the design concept. In reality, though, only a handful of putter designs were sold in any sort of volume quantity.
The Anser 2, the B60, the Pal 2, and the Zing are Ping's most well known putter designs.
Back in the day Ping offered putters in bronze, stainless steel, copper, and for a short while, nickel.
Most of the putters were offered in the bronze or steel or copper, or two out of three. Nickel was a distant fourth as that material was more of an experiment which Ping only sold for a few years. It turned out the nickel was too soft sounding and dinged up too easily for most players taste.
Eventually the copper and nickel were discontinued because of environmental hazardous waste issues. The bronze has gone out of fashion these days.The newer model Ping putters are steel with various bead blast media finishes.
