The pen is a vintage Parker that was presumably made before 1945, in the 1930s, in the USA. Counterfeits of historical Parker writing instruments of this construction have so far not turned up, so the authenticity risk is low. The housing consists of celluloid; the nib is solidly made of gold. To be noted is that the Vacumatic filling technique is hard to repair in Europe, since corresponding special knowledge and tools are seldom available.
