Bobby were your extractor barrels as different from the ejector barrels as mine? I had to have mine altered by a milling machine. Might have done the job by hand given a lot of time. Don't know if early and late barrels were much different for extractors and ejectors, they all were not an easy fit. One thing I learned is to inspect the face of the barrels a lot closer.

I cheated in picking a ejector gun which the barrels almost fit and having three orphan ejector fore ends to work with. To try this job with just any set of barrels would have been beyond my abilities and patience. Had I left them as extractors I would never gotten myself into half as much a challenge.
