most of what one gets in a Callahan letter on a Sterlingworth is a regurgitation of the catalog listing....... and what you get is that the catalog says a Sterlingworth Standard is full and full. Throughout the Philadelphia years the Sterlingworth Standard was catalogued as full and full.
I own three Philadelphia Sterlingworths, a 12 gauge, a 16 gauge and a 20 gauge....(1929, 1925, 1926).......all three letter with dimensions that match the guns at present........and to whom they were shipped with a date.....
All three are choked modified and full and letter as such..... All three still sport the factory butt plate and match the letter wood dimensions given.....so I guess I didn't get any 'Sterlingworth catalog' information form letters of which you speak........
Sorry, I don't own or want any Savage built guns.....
As far as Cody goes, as a member, one has access to work sheets for pre-buy confirmation on any gun they have records on....confirming dimensions etc.....before you buy the gun.....I don't consider Cody's information bad whatsoever......
