Here are the specs that the seller gave me;

> Greener cross bolt, action tight, on face, no wobble.
> 2 3/4 inch ! not 2 1/ 2 inch
> proofed for 1 1/8 oz loads
> choked 1/2 and 5/8
> Reddish English walnut to horn buttplate
> good scroll engraving
> 6 1/2 lbs
> marked " New Barrels by Carswell" ( If it's sleeved I can't see the joint.)
> Proofs indicate proof after 1925 and again after 1989
> R Jones located in Yorkshire thru 1990, while Carswell was from Liverpool.
> Shotgun has both Birmingham and London proofs. Carswell purchased Jones, exact date unknown, but relatively recently.
