I've sold and owned many Filarmonica 14s and the one you are showing is definitely a second generation model the first generation models I believe were made in Germany and that's why they didn't stamp the country of origin, secondly if you held them both in your hands and looked at the first and second generation models you would see that there's a noticable differance in quality from the scales to the blade etching and tang stamps, also the scales and Lyra are completely different on first generation models the scales are made from high quality materials and not that awful cheap nasty plastic as you find on second generation razors, here's my last first generation 14 came with the guarantee and all the paper work something I've not seen before, plus here's another first generation I sold a while back a 14 Especial both these razors are pre 1950s.
PS forgot to add the inlay Lyra on the first generation models are also made of metal I believe it's nickel silver.
