please see the picture of the rear dropout on my 1951 Girardengo. The Name of the Lug maker has been filed off during a rechroming job. I guess it is a Simplex (The Dropouts on the fork are) but trust me, the dropout is the original one, i personally scratched the original paint off it.
Question @Listmembers: possibly one of the oldest frames out there with this style dropout?
