Character fox HN866.

From time to time one spots familiar items mounted with various Doulton wares and such was the case when I recently saw this Dickens miniature of Tony Weller mounted on a genuine Shagreen base together with a sterling silver stamp holder or stamp moistener (the moistener missing), just like mine with the fox above. 

 
Tony Weller HN544.
Here is a further example mounted with a very rare character Beagle, a very early Doulton animal currently available from Seaway China. 

 
Character Beagle HN831.

 The sterling silver mark on the stamp holder gives us the year 1923 as the year of production.
