Do we have a number on the L.C. Smith Wildfowl/Long Range guns? A quick look in Houchins this morning while my oats were cooking, I didn't see one.
The count of their records Ithaca Gun Co. did back in the 1960s showed 87 12-gauges built on the NID magnum-frame. The Magnum-12 wasn't listed in the Ithaca Gun Co. catalogs until 1937, but we see 12-gauge guns throughout the 500000 serial number range. However, some of these 12-gauges built on the NID magnum-frame that have surfaced have 2 3/4" chambers.
A.H. Fox Gun Co./Savage Arms Corp. built about 950 12-gauge HE-Grade Super-Fox guns but how many started life chambered for 3-inch shells is not known.
Some other manufacturers tried their hand in the field as well. Davis Warner Arms Corp. offered one of their N.R. Davis doubles which they called Hy-Power Grade --

The Hy-Power Grade doesn't appear in the Crescent - Davis Arms Corp. paper from the 1930s.
