If your most recent score has three daisy wheels on the kettle, it's not a One Touch Silver, it's a Bar-B-Q-Kettle. The vents could have been replaced and therefore have an incorrect date stamp.
I have two 40 year old dual metal handled kettles that have lower vents with a date code of 2012.
The change from two metal handles to one wood handle was probably to reduce cost. The reason for the one handle and two handle kettles was to distinguish the OTG and Mastertouch from the OTS.
I think. But I'm a man. I can change. If I have to. I guess.
