The problem stems from the fact that, for the Armortec 700 Limited, Yonex did not use a common serial numbering system. For instance, the SP versions are serially numbered XXXX/5000 whereas the JP versions are serially numbered 7XXXXXX. In both systems, the date code system has been retained. Based on the number and date, petert1401's racquet is legitimate. If pictures are available, a firmer assessment would be possible
