I picked up a grey Craftsman at Hedgerows GTG last weekend that is supposed to have thin rings. I haven't had time to pull the muffler yet to verify it, but for $25.00 who cares.That's interesting. There's a grey 3700 a few pages ago here. Canadian saw though, labelled 3.4 and bought from the original owner. My grey Craftsman 3.7 is a 3800.
