Greetings all.. this is my first post on this board, so please bear with me. While I'm no stranger to H&R in their various forms( Cut my teeth on a model 58 topper in 12 gauge

) and I own a handi in .243 and an ultra in 25-06, I seem to remember seeing a reference somewhere to serial numbers and year of manufacture. Of course, it is also entirely possible that I'm having a "senior" moment as well.. Has any one else heard of this ?? Thanks in advance!
