I have a Win. 1906 (made in 1911) with a bore that can only be described as totally rotted inside... it has craters and worse in there. I've never missed a soda/pop can at 25 yds with it..... With treasures like these, I overlook the bad bores and just treasure their 'history' and classic looks. Don't overthink... BUY IT.
IMHO,
J.
