It being bought from Jedediah Starr it could have been on the shelf awhile. That's not a criticism I just think a lot of folks wanting a newer gun may use bigger shops like Midway? Odd that there isn't a date code present though.
No date code and the CIP/PN stamp instead of the PN under a star says it's a newer gun. It probably has the year under the trigger guard and may possibly have a date code somewhere else like under the lever.
I just looked under the lever and sure enough, there it is! 2022. It probably has it under the trigger guard too, or somewhere else hidden on the receiver.
