actually both dates are true. Penzel company was established in 1882, and in 1884 E. Mueller who was Penzels cousin joined company. Company was renamed to Penzel-Mueller in 1890, BUT when Pruefer joined company in 1914 it has been known as Penzel-Mueller-Pruefer. Louis Penzel died in 1920, Pruefer retired from partnership, and Mueller renamed company back to Penzel-Mueller.it seems to me that since Penzel-Mueller was formed in 1899 (some say 1920)
Phil has to be right if you look at the features they are missing on horns produced by PM in 20s, 30s and 40s.I have a G. Penzel Pacmaker, s/n 5229B, so it's slightly older than yours. You can read a review of it on Clarinet Pages at http://www.clarinetpages.net/vintage-odd-brands/penzel-g-penzel-pacemaker. Phil thinks it is newer than I do; it seems to me that since Penzel-Mueller was formed in 1899 (some say 1920), that a G. Penzel horn would predate that, but who knows?
looks like he might be K. Gerhard Penzel, german bow maker of father and son "K. Gerhard Penzel und Roland G. Penzel" (and since Roland joined business in 1970s, it would have been just G. Penzel prior). Family business owned by the branch of Penzel family which stayed in Germany.Perhaps G. Penzel is descendant/relative of Louis Penzel? Or G.Penzel is what came out of ashes of Penzel-Mueller bankruptcy in late 1950s.
