Ithica shotgun

[Chuck7]

Hi,
I have an old 37 Ithica 12 guage. I was wondering if I could just by any Ithica model 37 barell.{Serial number 596028-2}

The reason I'm asking.Cabelas was selling them along time ago but the serial number had to be over 700,000. I hope someone can help me out. I need a new barell.the gun was left to me from my grandfather.I'd like to buy a 3" magnum if available.
Thanks,C7

Whether the barrel will shoot 3" or not is not the question. If the receiver does not support 3" than you can NOT shoot 3" through this gun.
