This model was made for the British during WWI although some were sold commercially. The stocks have been replaced on both. Originals were checkered walnut. Close up pictures of the rear of both cylinders would be helpful when the experts find this post. A good number of these revolvers were converted to .45 ACP or .45 Colt. Both are missing the lanyard rings but are in generally good condition if the bores, charge holes and mechanics are in similar shape to the exteriors. S&W put service date stamps on the left lower frame, which would be covered by the stocks. An example, if this was still being done today, would be 5.25 for a gun serviced this month. Any of these can affect the value positively or negatively.
