Western Field lever-action .30-30 rifles were made by Marlin. TexasCharley -- EXCEPT for this one -- The Western Field Model 79 is actually a version of the Mossberg Model 472 lever action .30/30. They sell for $150-$200 retail in VG condition. sales@countrygunsmith.net
I can say that the Western field model 740A is the Marlin model 336 lever action rifle that was made for Montgomery Wards(Western Field).These rifles are valued at between 200-300 dollars,depending on the overall condition and a good bore.
Various other websites list this as a Western Field brand sold at Montgomery Wards but manufactured by Mossberg (hence the M in the model number). The Mossberg model number is 402
You must have a Western Field Model 72C lever action rifle, which is a Mossberg 472C. Try gunpartscorp.com or eBay for an owner's manual. A repair manual is going to be tough as the gun is not well known.
The mossberg model 45A is the same gun as the western field model 47.

The Western Field model 72 lever-action rifle was made by Mossberg and generally resembled the Marlin 336. These two rifles are not the same an no parts interchange EXCEPT for the scope mounts. The same bases that work on the Marlin 336 will work on the Western Field (or Mossberg or Revelation versions).
I recently bought a late 60's Western Field Model 740-A-EMN in mint condition for $275. The rifle was manufactured by Marlin with slight modification of their Model 336 there a few cosmetic differences in particular the sites. Otherwise the operation mechanism seems identical.
The Western Field m72 was made for Wards stores by Mossberg from the early 70's to the early 80's. value $150 to $300 depending on condition.
