It is not a straight line, you can't find two points and draw a line between them!! Seems like someting was changing every year.

In 1936 J. Stevens Arms Co. began phasing out their old G.S. Lewis Patent 1,136,247 action with coil spring driven strikers guns, the Stevens No. 330 (or 331 with single trigger), and the Springfield No. 315 (or 315ST). These were replaced with the new 5100 and 5000 actions and became the Stevens No. 530 and the Springfield No. 515. The main difference in a 5000 and 5100 action is the sculpting of it, most of the internal parts are the same. The Springfield No. 311 continued to be made with its plain walnut finish stock and forearm on the old G.S. Lewis action. In 1940, Savage introduced their Fox Model B with a bit nicer profiled action, but many of the same internal parts as the 5000 and 5100 actions. Prior to WW-II the Stevens No. 530 had a capped pistol grip and the various Springfield No. 515s had no cap, but both guns had checkered walnut stocks and forearms. Then in 1940 they introduced the Stevens No. 530M with the Tenite stock. That remained the offerings through 1946. By 1947, Savage had consolidated their arms making operations at the old Stevens plants at Chicopee Falls, Mass., and in the 1947 Savage/Stevens/Fox/Springfield catalogue the Tenite stocked double with the 5100 action was called the Springfield No. 311. By the 1948 Savage/Stevens/Fox catalogue the Tenite stocked double was being called the Stevens Model 311 and they no longer mention a cap on the grip of the Stevens Model 530. By the 1951 Savage/Stevens/Fox catalogue the Tenite stocked gun was gone, and the Stevens Model 311 had a plain walnut finished wood stock and forearm, the Stevens Model 530 had a checkered walnut stock and forearm and the Fox Model B had a checkered walnut stock and forearm with a capped grip. The Stevens Model 530 remained in the offerings through 1954. By 1955 it was only the Stevens Model 311 and the Fox Model B and the new Fox Model B-ST.
