The Sears Ranger 101-14 rifle was manufactured by the Mossberg company. It was sold under the Sears brand name as part of their catalog offerings in the mid-20th century. The Ranger series included various models, with the 101-14 being a popular choice among hunters and sport shooters. Mossberg produced a range of firearms for various retailers, contributing to the widespread availability of budget-friendly rifles.
The Sears 30/30 lever action was manufactured by Winchester Western.
Ranger was a Sears Roebuck trademark. The guns were manufactured by several makers. If you have a model number, it may be in a cross-reference list. See http://www.e-gunparts.com/crossref.asp
Marlin
The model 36 .22 caliber rifle was manufactured by Marlin. It was the same rifle as the extremely popular Model 80 by Marlin.
The Ranger 101-16 .22 rifle was manufactured by the Marlin Firearms Company. It was produced in the mid-20th century and is known for its simplicity and reliability as a lightweight, bolt-action rifle designed for youth and small game hunting. The rifle was often marketed under the Ranger brand, which was associated with various retailers, including Sears.
The JC Higgins Model 31 rifle was manufactured for Sears and Roebuck by Hi Standard.
The Model 53 30-06 rifle was manufactured for Sears by Winchester. It's a cheaper version of their Model 70.
The Ranger 22 long rifle 103.13 was likely manufactured by Ranger Arms, a firearm manufacturer that produced firearms in the early to mid-20th century. Ranger Arms produced a variety of firearms, including rifles and shotguns, and were typically sold through retailers such as Sears, Roebuck & Co.
My best estimate would be Stevens.
There are probably some Ranger and Eastern Arms models that are identical since Sears owned both tradenames, but there was no actual manufacturer named Eastern Arms. If any Ranger firearms were made between 1905 and 1915 they would have been manufactured by Meriden Firearms, but most of the later ones were made by Savage/Stevens.
Store brand for Sears IIRC
