My Kings Ferry Ithaca’s use Winchokes, but my guns are/were 12 gauges. I ordered my extra chokes from Trulock.
I believe the kings ferry 20 gauges still used Tru-choke threads/chokes.
These are available from Trulock as well.
The Sandusky guns use invector plus threads but the bores on the Sandusky guns are not overbored like Browning inventor plus barrels.
I went to the TruLok website and found the choke tube interchange chart and the Kings Ferry guns do in fact use the Tru Lok Tru Choke standard pattern in the 20 gauge guns. Thanks for the TruLok reminder. I just placed my order for the two that I need. Thanks to all for the help.
