Thanks Joe. That's the info I was wanting.
The stock is most definitely a replacement. Several dealers (yes, they are in business to make money) at the Louisville show said a IHC stock will run $500-600. At this point I guess I'll be satisfied with what I've got. Maybe a stock will show up some day at a decent price.
As of now every part (that's identifiable) is IHC and correct for the serial range except the op rod. Its a 65...IHC.
Thanks to all that responded. I'm just glad I could bring this one back "home" to Evansville.
