winchester carbine

[W5USMC]

In your generous effort to help, why didn't you include info from the disclaimer preceding the table?

Oh OK firstflabn, "All listed serial numbers should be considered to be approximations and are not exact" although I kinda figured the word Approximate would have made that clear.

@cpc, Here is some info that is more exact, On 20 April 1945 the following serial numbers were applied to Winchester Receivers 6578421-6579800, note that this is when the serial# was applied to the receiver not when the carbine was complete.
