54 Sporters definitely have a following. There are several variations. A few that would mean higher value for you included:
long tang trigger guard
banded barrel for rear sight
bossed barrel for front sight
23.5 inch barrel
And as always, nice wood.
They are great shooting rifles. Go have some...
Depending on budget, my two choices would be a Weaver V16 ($400) or on the higher end a Leupold VX6 4-18 EFR. That Leupold has the most clear and crisp image I have ever viewed.
