I feel like I am on a gameshow.

Patrick, Yours and Doc44's combine synopsis is 100% correct. Final answer for the win. I am locking it in win lose or draw. I came here to win big or go home

28-2 N prefix meets donor S prefix 29 for a barrel and cylinder swap. Most likely the 3 T's were added but could have possible been ordered on a 28-2 just as RR and WO could have been,, although highly unlikely,, and if that barrel measures a whopping 8 3/4 as stated more than once in this thread by the OP instead of a standard 8 3/8 Ill eat it and put it on youtube for everyone to laugh at me and call me names. I came on this game show with nothing and If I leave with nothing,,,, well I broke even.
