Yes, Stevens. The 330 was a nicer model of the 315. The first model 311 was the earlier design also. Following is a canned response from researcher:
"That G.S. Lewis Patent No. 1,136,247, granted Apr. 20, 1915, action, which used coil-spring driven strikers rather than hammers which rotate about an axle, started out prior to WW-I as J. Stevens Arms & Tool Co.'s lower priced line the Riverside Arms Co. No. 315. J. Stevens Arms Co. continued to offer the Riverside No. 315 after the Great War. After J. Stevens Arms Co. was acquired by Savage Arms Corp. they added a slightly nicer gun on the G.S. Lewis action the Stevens No. 330. From 1923---. By 1930 they gussied up the Stevens No. 330 a bit
In 1929, J. Stevens Arms Co. changed the name of their lower priced line to Springfield Arms Co. For 1931, they introduced an even cheaper version called the Springfield No. 311 with a plain wood stock and forearm. By June 1932, J. Stevens Arms Co. introduced the option of a non-selective single trigger on these guns.
For 1936, J. Stevens Arms Co. began phasing in a new action with hammers that rotate about an axle, and the Stevens No. 330 was replaced by the No. 530 and the Springfield No. 315 was replaced by the No. 515. The No. 311 and numerous "trade brand" guns continued to be built on the Lewis action up to WW-II."
Your.410 has the Lewis patent action. The forward frame pin is lower than the rear pin. The newer design, with hammers, has a high forward pin, low rear.
