Thought that might get a laugh or two. Rick got me thinking about my 250 Savage T/D the other day. I checked my new edition of Murrays book and started adding things up. What got me thinking was when Rick said, if its a 1921 gun it would be more difficult.....Well Rick my 99G might be a 1899 250-3000 instead cause its a 1921 gun. So here we go....Going off of the descriptions on page 3-29 and 3-43 this is what I have

Model marking Top of Frame Ring " Savage Model 1899" in two lines.
Forearm length 10 1/8 inches
Barrel length 22 inches
Integral front sight small bead
Rapid taper to barrel but full threads like a "G"
Pistol Grip stock but no perch belly and there is checkering
Buttplate is corrugated steel shotgun style with savage indian in oval at the toe.
Serial # 2373XX
Barrel marking Savage Hi-presure Steel with 250-3000 underneath and the arrows on either side. This is on the LHS.
Trigger is not cross checkered like the 1899, it is serrated.

All of the numbers match. So which side of 1921 is this? Is it a 1899 250-3000 or a transition 99G?
