John, from your serial number the gun was made in 1889 and would be a very early Fulton hammer gun. I believe from my research that the Syracuse line of L.C. Smith hammer guns stopped at serial number 25,500.
This gun is identified as having a 5 pin lock with the rotary joint check. It would have the high type 1 hammers and be a bar action lock, meaning the mainspring is before the action or tumbler (hammer). Finding a stock would be hard but keep your eye open at auction sites or eBay for one. Does your gun have a squared barrel lug or rounded corner? This is the part that enters into the receiver. The receiver would be squared also.
Jerry Andrews (304-843-1740 Moundsville, WV) might have all that you need. The firing pin would be the easiest to find.
