Yep... they are out there. I also have an early Ideal 10ga. with Damascus barrels with Curtis for-end.
It sounds like your anxious to shoot when you get it. Who wouldn't be? As to what it's like shooting a ten... When you first get it, grab some RST 2 7/8" 10 ga. #7 1/2 shells and take it to the club trap range and shoot from 16 and then from 27 yards to see the potential of the mighty ten.
