These allocations suggest serials 8304,8313,8314,8324 and one between 8302 and 8306(other than 8304) have not been used.
Use of serials ending in 4 is seen as bad luck in some Chinese-oriented societies.Avoidance of 8313 speaks for itself.
The Republic of Singapore Air force avoided the use of serials ending in 4 in their Chinook allocations.
