The Weatern Arms Long range Gun was made and marketed by Ithaca as an economy version to the Lefever Nitro Special. Some posters above are confused with names like Western Field and others similar to it which were trade names used for other retail stores.
Stevens/Savage had nothing to do with the Western Arms guns that the OP asks about.
There are some minor differences in the actions and barrels that make interchangeability with Nitros difficult, but the forends are the same.
The forends are different between the different gauges. Or, at least 12g is different from the 16/20g irons. But i am not sure if the 410 is unique or not in regards to width at the frame. I have a few new old stock 16/20g irons. If someone can get me dimensions of a .410 iron at the rear, i can compare them to the 16/20 to see if they are maybe suitable for modification. I know the irons on the .410 are shorter, but i cannot verify if the lug locations are the same or not.
Either way, i do have a piece of semi-inletted forend wood for the .410 if you are able to locate an iron.
