Can a sterlingworth barrel be installed on a A grade 12 without a lot of modifications

Maybe.

Forearm lug needs to be removed from the Sterly barrel and replaced with a graded lug. Good smith can do it. I almost did it on a 20 gauge before I found a graded barrel.

You can use sterlingworth or graded snap on forend if you do not want to change lug.Bobby

Correct me if I'm wrong Bobby, but the snap on graded forearms were only on the earliest 20 and 16 gauge. So if you have have a sterly 20 or 16 gauge barrel it will fit on a early small bore graded gun only.

Also, the early small bore extractor guns, both Sterlingworth and graded, used the Fox & Kremer latch snap-on/-off forearm --
while the ejector guns used the F.T. Russell latch.
Later the extractor guns began using the F.T. Russell latch as well.
