Haven't you read that an Ithaca Flues is:

"It is truly a vile affront to proper engineering. Like all Ithaca guns (and all American guns), it was available in some high grades with very well done engraving. Sadly, the engravers' work is all but wasted on this very poorly designed farm implement."

Thus spake Zarathustra.

Buy these ancient pieces of junk at your own health and financial peril.

Out there doing it best I can.
