The true Ithaca 12-gauge 3-inch magnums were built on the same long NID frame, with the lug through the bottom, as the Magnum-Tens, with serial numbers from 500000 to 501011. The accounting Ithaca did back in the 1960s, showed they made 887 Magnum-Tens, and only made 87 Magnum-12s. Ithaca Gun Co. didn't begin cataloging the Magnum-12 until their 1937 catalogs, the first catalogs without the Super-Ten. However, I've recorded Magnum-12s with serial numbers as low as 500144, a No. 2E at the Cabelas flagship store in November 2002. Had a ring bulge behind the choke in the left barrel. The Magnum-12s were cataloged with 30-inch barrels, but I've seen them with 32- and 34-inch barrels. The No. 2E I mentioned above had 32-inch barrels and this No. 1 --

has 34-inch. The only $1000 grade NID was this Magnum-12 Walter Snyder did an article on in the latest
