My Ca 1893 Lefever "Two Hook" 12 has 2 5/8" chambers. All of my "Large Hook" guns have 2 3/4" chambers & at least by the time of the 1913 catalog it was stated 12ga guns have 2 3/4" chambers unless "Otherwise Ordered".
My one 16ga (post 1907) has 3" chambers as does my one 10ga (early rod cocker ca 1889). Rechamber?? When would either ga have likely been "RE-Chambered" to a 3" length?? 3" was never a "Standard" chambering in either of these ga's & would have been more readily available around the time they were built than in other later point in time.
2 3/4" 12ga guns were much more common around the turn of century last than many seem to want to believe.
Funny thing, I don't have a single Lefever with that "Infamous Crack" behind the rear tang screw.
