I've never seen a Parker (with the original stock) with "poor head to action fit." The damage was most likely caused by mishanling of the gun or falling on it.
I was referring to wood shrinkage over time, specifically to the Head. It's not unreasonable to think it would occur over a period of 100 years or more. Oil soaking could also weaken the Head. Since cracked heads are so common, I find it hard to believe so many guns were dropped so hard as to cause the heads to crack. Us "Bottom Feeders" run into cracked Heads all the time.
