One noteworthy item on this double is that it is fitted w/ Witten Excelsior tubes made by one of the best of the best tube mechanics, Johann Werner Gottgetreu of Suhl. He was born circa 1840/1841 and expired near the end of WWI in 1919. Regarding The Daly Gun, I believe he was the main source for Witten Excelsior tubes and for the moment I'm not sure just how he had that niche market.
