I'm pretty sure it was a 2F. I will not be able to look at the gun for a couple of days. Also on the barrel flats were the markings B/P and LLH. The forend also had an S in front of the serial #. The top of one barrel said Made in USA the other Smokeless Powder Steel. Maybe someone with some Ithicas can help. I'll let you know as soon as I can get back to look at the gun. Thanks
