Utica Firearms was a trade name used by the Simmons Hardware Company of St. Louis, Missouri on firearms they retailed circa 1900. It could have been manufactured by any of a dozen makers. Like any other 100-year-old tool or machine, parts are where you find them. You may be able to get parts that fit (or can be made to fit) from a local gunsmith or at a gunshow, but no one will have a catalog number for "Utica firing pins".

The bible for info. on older shotguns made by other than the big name manufactures is the "Golder Age Of Shotguning" by Bob Hinman. In the index of this book he lists literally hunderds of old brand name shotguns along with some info on the co. Unfortunatly all he has to say about a co. called the Utica Firearms Co. is "Hammer double-barrel. Nothing further known." He must have put an extreme amount of research into this obscure list of manufactures (and this was 30 to 40 years ago) and to have come up with "nothing further known" is not very incouraging. My guess is that this Utica Firearms Co. is the manufacture of your shotgun.
Guns marked "Utica Fire Arms Co. Pat. Nov 25,'09, March 29,'97" were made by Hopkins and Allen Mfg Co, 1868-1898. If your gun does not have these patent dates, it was probably made in Belgium, c. 1880-1914.
If it is marked "Utica Arms Co.", compare it to a Crescent Model 6 (1903-1930) or a J. Stevens Arms Co early Model 311 (after 1920). The Stevens might even be marked "5000", "5100" or "311" on the receiver. If marked "Utica Firearms Co." or "Utica Special" it should be the Crescent Model 6. Those marked "Utica Firearms Co. London Fluid Steel" are also by Crescent, but should have outside hammers and could date back to 1892, but probably made no later than 1914. With the mark "Utica Fire Arms Co. Pat. Nov. 25, '90, March 29, '97" it was made by Hopkins & Allen Mfg Co. (1868-1898, but the patent date would indicate these guns were made in 1897 and 1898) I'm not sure if these were single or double barrel guns. All were made for Simmons Hardware 1875-1940
