After all these years, I just got one - this makes my 5th Marlin "keeper". Thanks to NSERIES! A great guy to deal with. Not really sure if it's a T, barrel isn't marked T but it's exactly what I wanted - 20", straight stock, squared trigger guard, no saddle ring. I'll have to check the S/N for production date. Actually, I don't really care what it's called but it handles like a Winchester and is built like a Marlin. Had to tell somebody...
