Bought a Repo new in 1987. In a year the stock split at the wrist. Had it repaired well. Short time later, the single trigger malfunctioned. Had it converted to DT. That bcured everything. Sold it...No Mas! Two other folks locally had Repros that also split at the wrist.
There are quite a few original Parker guns that are pinned or doweled through the stock cheeks, or have been restocked due to splitting. The wedge shape of the tang, along with recoil contributes to this. It happened to my VH grade Parker.
So when you make a near exact reproduction of a gun with a design that is prone to a certain problem, why would it be surprising to see the same problem occasionally in the repro?
Some L.C. Smith stocks are known to often crack behind the sidelock plates. Some Lefever stocks are prone to cracks or breaks above or below the sideplates just behind the frame. Some Ithaca Flues stocks have a piece split out on either side of the top tang. Not always... but often enough to be noticeable and keep stock repair guys busy.
Design deficiencies or errors are a common thing that sometimes gets corrected, but often doesn't show up until many years after an item was sold. Most of our vintage doubles are pre-WWII and older, and are still going strong. There are very few consumer products that old that are more trouble free than our old guns. Our vehicles fail and get scrapped en masse all the time. Our guns get scrapped en masse only in countries where anti-gun politicians get elected.
