I have 8XX-MR shipped January 24, 1961, and its original box is the regular telescoping wood grain box with the green inside and yellow end label with black lettering.
A very late gun may have come in a different box, perhaps even a "Trophy Box" like the one pictured. I do not know about the later guns.
I believe the serial number charts are wrong in regard to the later serial number ranges, but, until someone letters a late gun like the ones mentioned, I am not sure what will be revealed about shipping dates.
dant, is your gun a .38 or .45? The reason I ask is that the box types may be different, although I doubt it.
