The value of a 22 SLLR Sear Roebuck model 42-103.19791 depends on its condition. This gun in excellent condition is valued between 85.00 and 125.00 as of 2014.
SLLR indicates that the weapon is chambered for Short, Long and Long Rifle rimfire ammunition.
Not sure the question are you looking for the model, manufacture date or what? Is it a pump, bolt, or???

I can't find a cross reference to the Western Field mod 804. If you can identify the manufacturer of that rifle (because Western Auto did not manufacture any guns - they bought existing models from a variety of manufacturers and had the Western Field name placed on them instead of the actual manufacturer) then parts can be procured from several sources. I suggest that you consult a gun values book to determine who made the rifle. Mossberg, Savage, Marlin, Noble, Stevens, and Colt all sold different guns to Western Auto. Possible sources of replacement parts are: Numrich gunpartscorp.com Jack First jackfirstgun.com Bob's Gun Shop gun-parts.com Order the parts by the actual manufacturer and correct part number. Some of these sites have exploded diagrams to assist identifying the parts.

I know of 2 for sale at $100 (and they are still for sale). I read an article on line that said $150 if it is new in box
