Orvis catalogs in the late 1890s noted a change from riveted to screw construction. Orvis called this the “improved” model and noted a stronger rim plate (“safety band”) was added to the No.2 bass model. This change happened some time between catalog #17 (ca. 1895) and catalog #22 (ca.1900).



However, reel collectors often use their own terms, labeling the evolving variations First Model, Second Model, Third Model and recently, Fourth Model (the No. 2 “improved” model for bass with the overhanging rim plate).
Here is a quick way to (usually) identify each of these four models from the rear plate:
First Model (rivets; no rear bearing cap, no patent date; etched patent date on foot)

Second Model (rivets; rear “button” bearing cap with 1874 patent date)

Third Model (screws; rear “nipple” bearing cap surrounded by printed patent info)

Fourth Model (screws; rear nipple bearing cap and drag/click button; reinforced overhanging “safety band” rim plate)
