In a couple of decades of looking at Husqvarna LeFechaux action hammer doubles with two shotgun barrels, I don't recall any that had obviously reamed bores (unless some American had it done after it was imported). These were utility guns in Sweden, NOT guns one spent a lot of money on, either to buy or subsequently.
Where I have seen lots of reamed shotgun bores is with Husqvarna LeFechaux action kombi guns. These guns cost much more and most were heavily used. Most show signs of repairs, often seemingly done by blacksmiths.
Husqvarna made numerous toplever hammer doubles. Some are quite nice handling, many basically copies of Sauer hammer doubles, perhaps using Sauer actions and other parts. These merit careful attention to how much they might have been reamed, either in Sweden or in USA. I have one where the right barrel appears to have been reamed at least twice. It still has more than adequate barrel thickness because the barrels are early fluid steel, made thicker than Damascus barrels because of suspecions about strength of early fluid steels.
