One of my hunting partners owns an Ithaca English Ultra that he bought when they first came out in the '70's. He killed over 500 grouse with it and "retired" it when he felt he had shot it out.
I much prefer the steel frame English guns and still own three of them (2-16ga,1-20ga).
The Kings Ferry plant was a 2 hour drive for me and I've been there on many occasions. They made a Supreme Grade 16ga. English gun for me around 2000. It has since gone down the road simple because I didn't need 3 16ga. Model 37's.
The "problem" with the Ultra's is that they are too light for me. They don't swing well and recoil is a real problem.
The steel receiver guns weigh 6lbs. in 20ga and 6 1/2lbs in 16ga. That's light enough for me.
