SGLover;
The only writings of W W Greener I have is his 9th edition & many things in it are from previous writings so hard to tell just when he said what. He does mention radial expansion as being a fault of an unbolted Doll's Head in that due to this expansion, according to him, it is lifted vertically from its seat upon firing thus losing its effect. Both Westley Richards & Dan Lefever used a bolted Doll's Head. Have never owned a W R so can't speak for them but this Doll's Head & the hinge are all the Lefever has. All are over 100 yrs except those assembled at Ithaca & they are near the century mark. All mine have remained tight over that century + of use.
Some of the top levers have gone a bit left but as mentioned this comes about from rubbing friction in opening & closing, not from shooting IMO.
Regarding ulcers I once knew a gentleman, now deceased, who told me he Cured his ulcers by eating Hot Peppers. Some time after he told me this I saw a Dr's report who had researched ulcers & he stated firmly that hot peppers were an asset in healing them.
