Argo:

I recently acquired a Box Lock extractor double marked E. M. Reilly & Co., 277 Oxford St., London. Serial number 23536. It is nitro proved for 2 1/2" 1 1/8 oz loads at the London proofhouse. Barrels are 30". They have been reblued, but I cannot see any Damascus steel pattern under the new bluing so I presume they are fluid steel. The action is an A&D patent with use number 3814 so marked on the action flats. The action looks like a Westley Richards profile with simple border and plain finish, and even has their toplever and beefy early cocking dogs. But there is no maker's mark that I can find. Thought you might want to add it to your serial number list. If you want pictures, I can email them to you. The gun is a shooter, not a collector. Russ
