Red Wing Hunter

[Margly]

Hi fellow bowhunters!
I bought an old recurve today with the name
Red Wing Hunter 45# and 58" from Wing Archery.
The regnr. on the bow is RW17772. Is there anybody that can tell me the production year of this bow?
The braceheigt it have right now is  6,2" what braceheight is recommended for this bows?
It looks old and used but shoot them arrows as smooth as anything i`ve ever tried.(actually i`ve never tried anything better)
This is a bow that really impressed me and i`m wondering if anybody have some experience with these bows?
