I have never had one. Some guy from Cracow posted those photos. I don't think he is a collector. Just a random man with awesome lamp... Especially important one because made for polish pre-war military. Look at the signature (it is mirrored). W.P. stands for Wojsko Polskie/Polish Army, SAN - sanitary purpose (made for the Mobile Army Surgical Hospitals)
