Found a Green and black box from bear Archery in grayling with several arrows at a yard sale for 10.00. The tag on the end of the box reads A-60 standard grade, point is H4, 28inch, 45 to 55 lbs,Fletch Z3671,  21/64 yellow $15.47. Can any one tell how old this is.

Thanks

Good find for 10 bucks. I'd guess mid 70s or so.
