Probably a parts gun, as some of the attributes aren't in sync with what Winchester was making in 1946.
IIRC, Winchester dropped the 32-40 and 38-55, along with the 94 rifles, from their catalogs in 1937/38. It is possible that this rifle was produced post-WW2 as a special order from a mix of pre-WW2 and post-WW2 parts.
