Just purchased a new set of T300 irons, box says produced in 2022. I assume that they’re the 2022 model?? Either way the clubs don’t match…the backs of the 4-7 have a M logo on them and the 48°-8 irons do not?? Is this the way they come or is this a mismatch from the factory? Additionally, there is no serial number on any of the irons. Should I be concerned? Thanks. Photo for reference
