Listed here are a well loved putter stack of classic chains aviars. I realize the one doesn't really have much of a stamp but can confirm that it is indeed a chains avair as well. These are well loved and feel soft for DX Plastic. Weights are listed below. Seems the previous putter put their nails into the rim a bit, and I showed zoomed in parts of some under flightplates.
