Ok! Upon further reading, Harry corrects his Flannery answer to be "We were getting all our barrels forged, rough drilled and rough turned from Belgium. We were purchasing them from either Samual Buckley & Co. or from J. D. Riga & Co. and it was not until two or three years later that we began purchasing those barrels from the Flannery Bolt Co."
Pete, you nailed it! Great work!
So.. Can we say that Ithaca barrels marked SB&Co. from this era were commodity Belgium barrels imported by Buckley and so stamped? And nothing to do with Sanderson Bros.?
