Bob,
There have been many threads on the ICDs in the past. A search may bring some up.
In short ICD produced less than 500 guns in two lots.
470xxx guns were manufactured in the US using parts supplied by Italian company.
471xxx guns were made in US with Krupp barral and receivers made somewhere I don't remember.
BEWARE-of guns made by an Italian firm with parts that ICD rejected. They look very similar but have reference to ICD or Victor,NY xx-ed out or absent. These guns are numbered in the 470xxx range and have caused a lot of misunderstanding which has unjustly tainted the reputation of ICD guns.

Bob, of the guns manufactured in the U.S be it Italian parts or the latter , what were the perceived differences (excluding the X'd out variety). Thanks
