Read an article a few years back about those Tonelli eights in shotgun news (or GunDigest). If I recall correctly, They were dedicated 8's and not a conversion. The article gave alot of good info, but also told the story about how the U.S. Dealer had been searching for these for years and once they were found, had to convince the european owner/dealer to let him import 50 of them to the U.S.A..

I'll dig up the article out of the stack (big stack) and see how bad my memory is...
