Most of the times, the so-called Doll's Head lock-ups (named after a certain Mister Doll, I was told, not after a child's dear toy?) do not really bear and lock anyhow.
But even when keeping this in mind, it is rare to see such a *wide* gap that Colonel Hathi and his whole jungle patrol could march through it in order, trumpetting loudly...

In fairness, the gun is quite old, old enough to have been used in a near frontier setting, by people who didn’t care what it looked like, only that it worked well enough to provide for the table. The tools might have matched the farm equipment, but, been sorely lacking at the bench the hapless gun found itself on.
To say it has experienced unqualified gunsmith work, would be to ignore the obvious.
Best,
