Where can you find schematic for wards western field model 47L 22 rifle?

Well, there is a problem. Your rifle is likely a Mossberg 45A made for Wards. These were made so long ago that makers did not furnish schematics. They expected a gunsmith to be able to fix a basic rifle without being told what to do. There is a Mossberg site under Epix Damguy Mossberg that has an illustration and parts listing for a Model 45B (very similar). Parts MAY be available from Havlin Sales through their website. These rifles are from 1937-1938, so parts may be scarce.
