I am sorry but...........
If you could, and I wouldn't try, get it restored to this configuration, it would have "collector value". I recently did just that with a later model Brit. I had about $125 in the project calling in favors and trading stuff for work. A commercial grade like this one would be three times as much.
We often refer to these chop jobs as Oswald Specials since he killed a Dallas Patrolman (J.D. Tippitt) with one after JFK and was caught carrying it.
S&W made .38 revolvers with unsupported ejector rods for three years 1899 to 1902. Unlike the Colt, S&W's rotate counter-clockwise which tends to push against the crane (out of time) and sometimes (more likely in double action) they begin to shave lead. Most of these are also reamed to accept .38 Specials. Probably not the safety issue some seems to think, but a second undesirable modification. Three if you count plugging the swivel hole.
The civil proofs are generally not much of an issue. If a gun entered commerce in the U.K. they were required and proof testing occurred at either the Birmingham or London Proofhouse. Only the viewer's mark survives on yours. There should be a number of crowned BNP (Birmingham Nitro Proof) marks as well as .38 .767 and 3.5 Tons (on the barrel). There were likely Enfield Arsenal acceptance and proof marks at one time.
The value of such a piece is probably best determined my finding one on Gunbroker.com (search Victory Model) and follow it to sale. Don't pay any attention to the astronomical reserves and starts. Find one that is actually attracting bids. Follow it till it sells or bidding stops.
I hope you accept this post as an attempt to give you an honest, objective, take on this piece.

P.S. The number you find on the crane, in the frame recess and inside the sideplate is the soft parts assembly number, not the serial number. The serial is found on the butt, back of the cylinder, front of the extractor, under the barrel and sometimes on the leading (narrow side) of the crane.
