A speculative purchase of a 130mm f5.5 Elior Doppel Anastigmat has led me to try to find out who the maker was. I have tried Google search and Vade Mecum. Has anyone ever used one of these or know who made it? I strongly suspect it is an enlarger lens as the thread is 39mm but a different pitch to the standard Leica fit. I have a fancy it may be from manufacturers Elgeet since it is a plausible name that they might have used but I can find no records to prove it.
