possibly a Win 73, does it have a brass block in front of the
the trigger guard on bottom of reciever? Top eject or side? Marlins will be side eject, Winchesters will eject thru top. Does it have a visible hammer? if not, then might be Savage 99 lever, any of these rifles can have an octangonal barrel.Win '73 would be in .32-20, Win 92's & 94's would be .32 Win spec, Both Marlins & savages were made in a heck of a lot of calibres too.
Pix would help dramatically.:dunno:
