I wouldn't be surprised if there are quite a few outliers from standard appearance as varying size groups of sets were overhauled by or on behalf of post-war users- the one I've had for some years is a mid-range serial (011514) generally standard AR88D, but has a thick and very crisply cut and punched (i.e. not a casual hobbyist job) aluminium front panel with fine wrinkle dark olive drab paint and engraved legends. It'd probably be nigh-on impossible to trace what has happened and whose (professional and private) hands a great many sets have passed through- they were outstanding performers in their time and continued to be useful and worthwhile sets long after WW2 had ended.
