Skb Serial Numbers Ithaca
Serial Numbers Office
We only have records of firearms that we actually imported. SKB Shotguns USA imported shotguns from the Japanese factory during the period 1988 to 2009. These shotguns will have our importer’s mark (G.U. Omaha, Ne.) on the left side of the barrel under the forend. In most cases, the shotguns will have a serial number prefixes of either NS, NSG, NA, and AS. We can also help with any current production guns, manufactured in Turkey that we imported. We do not have any records from other importers of SKB manufactured shotguns: • Ithaca Gun Company which imported from 1969 to 1978 • Mitsui (Chicago, IL) which imported from 1981 to 1984 • Weatherby which imported from 1984 to 2004 The SKB factory in Japan closed operations in late 2009.
All documents pertaining to shotgun production and exportation were turned into the Japanese government. You can contact us, with your serial number, and we will look up the date we imported the gun.

I don't want to burst anybody's bubble, but, for the most part, the parts on the new SKB's are interchangeable with the old Ithaca SKB's. Like all O/U's, parts need to be more or less hand fitted to the individual gun. I recently broke a top ejector on my Ithaca/SKB 700.

After a call to Gun's Unlimited, I had a new ejector in days, and another couple of days for a gunsmith to fit it. If you look at the schematics on the SKB website, you'll find that parts for the Ithaca/SKB 500, 600, and 700, and the SKB 500, 505, 585, 600, 605, 685, 785, and 885 are the same. The 85TSS has a couple of modified parts, but very few.
The SKB is a modification of an old Merkel design that hasn't changed much since the 60's. Just found a model 600 28' at a local gun show for $350!!! The guy told me it was a 'skeet gun' (barrels marked full and impmod), also was told it was bored out to take 3' shells (forcing cones were lengthened and polished). Gun was probably 95% condition. Shot it yesterday (in a typical U.P. Spring gale) and hit 22/25 (not bad for a strange gun). I learned to shoot trap w/a century single from SKB.
Wish I still had it, just for fun. SKB's are good starter guns, and largely underrated. Just purchased older skb w/ no identifying marks on top of barrel either side of very wide broadway vent rib. Only proof marks are - left side of barrel by chamber: 'M7IV' over '891' - right side: 'SPR' over 'SPR' - bottom of barrel: 'K' then the serial number '708XXX' then '6' then 'NP'. The only markings on this o/u shotgun that identifies this firearm other than the actual way it was manufactured is the buttplate w/ ' SKB ' lettering on it. Nothing about Ithaca.
The shotgun's entire receiver,trigger guard, and top end of barrels near the chambers is intricately & highly engraved by hand ( deep relief ). Can anyone help to identify what model? Serial # on reciever is 'CM708XXX' on bottom within the cavity made for it. Also I need to replace some of the trigger parts, the trigger itself w/ selector as well as bottom firing pin and bushing/retainer and possibly both sears. How long did it take for skb Omaha to rebuild your shotgun? Thanks for any info.
