awww I wasn't going to cloud the issue.
Technically no there isn't, but obviously if you have a date near the limit of accuracy (ie say it is +/- 50 years) then you will have indeterminate results.
Using a WW2 base though you could be able to determine the age of the wood with direct historical documents (bills of sale, back to lumberyard inventory) to find actual ages
The concept here is to use C-14 to find apparent age that differs from actual age.
Civil War would be good, as "wood" the War of Independence (I used to rent a house that was originally a barracks ... for the british ... )
