I tried the recommendation from folks here to use raw linseed oil, rags and a tooth brush to clean the stock. About 30 minutes of care eliminated the matt mottled spots on the stock and brought out the tiger stripe. Very happy with this rifle.

This first pics shows the stock before a oil:

Here's after some oil and rubbing...I suspect more oil and friction would continue to clean the stock. The checkering is better after, but no where near as good as the pics shared under the stock cleaning thread.
