Westley Richards inscription is not shown in any of the pictures.
Both barrel and action have German & British proofs.
Looks like someone poorly bedded the metal.
Per Jon Speed's s/n list, if this is an Oberndorf commercial action it would have been produced in 1913, which doesn't match either date on the action. (??)
There were no pictures of the bottom metal.

If you right click and open the pic in another tab you can then zoom for a closer look.

This is the auction house description.
