Have you tried Numrich? There are a couple other firms that have been mentioned in others posts that have old S&W parts. I expect a Victorty Model lanyard would be the same thing.
S&W lanyard swivels (rings) are the same for K and N Frames. ( Victory Models, Model 1917s, etc. ) You will need the swivel and the retaining pin to properly install it in a Model 1905 K Frame. Ed.
