I agree with gasgunner, the quality of the work, particularly the checkering border lines, are not the quality I have seen in any other pictures of his work. Whether the patterns were fancy or plain, his border lines were perfectly straight or smoothly curved and the straight border lines of point patterns were part of the other checkering lines and didn't intersect them at a shallow angle like some spots in the patterns on this stock.
The poor wood to metal fit of the bottom metal, nose cap and recoil pad could be from a poor refinish job somewhere in the rifles history, maybe done at the same time as the rebarrel job, and not Mews work.
I wonder if this stock could have been made near the end of his career? As the arthritis in my hands got worse with age, my quality of work slowly diminished. On the last checkering job I did before I quit, probably half the total time spent was used for straightening lines when spacing the patterns.
