Bill,I went through the "Serialization Book" and there are 22 SBT guns listed with 30" barrels and straight grip stocks. That equals "not a lot"
While I was doing the research I found 6 28" guns,4 SBT with ball grips"Oh my!" And ya ready for this..1 20 gauge with 34" barrels serial number 178050. I hope that was a misprint or I am on a new quest..
I need to get a life.....
