Of the three different cross reference list I examined.The host's list.www.wisnersinc.com and www.hoosiergunworks.com, only one showed this model as a Ted Williams Model 100 and that was the Hoosier chart. Both GPC and Wisner's listed a 'Sears' Model 100 as a NM94 by Winchester as well as a series of M-94 that carried the Sears Model 54 designation.All should carry the Sears product code for Sears.273.xxxxxx with the 273 designating 'Sears' and those digits after the decimal point catalogging specific features of the product.like barrel length,finish,sights, swivels etc.
