Ithica NID 10 gauge 3 1/2"

So if it isn't marked as such on the barrel flats it's 99% that it isn't a magnum ?

That Askins gun would be okay to have ! Keith never carried much weight with me . When I was growing up I was more of the O'Conner school .

To be honest the reason I asked , Vintage Firearms in MI has a Grade 2 they say is the Magnum and the seriel number is 500,6xx but the barrel flats have no markings leading one to believe its a 3 1/2" gun .

The serial number and the frame style and measurements would be the final answer. The lack of chamber length markings could be an error at the factory.
