Hi All Today I am going to share my experience with my new(new to me ) Parker 51 Vacumatic . I have bought it from Pen Hospital Kolkata. This was my first visit to pen hospital. The seller is nice and well behaved person. First I have dealt with Sheaffer snorkel, but I have changed my mine after testing the Vac. It cost me Rs 5000(Around $78). This is single jewel pen with a blue diamond in the cap. And the cap is 14 Kt gold plated. And the ring near section is golden(generally we found silver color). The section of the pen is black and engraved with "PARKER 51 MADE IN USA". Nib is fine-medium . It is made of gold and dated 1947. Nib is very smooth in fact this is the smoothest nib I have ever used(I own Waterman Carene, Pelikan M200, Pilot Metal Elabo). May be I should thanks previous owner of this pen . Seller said everything is original(including vac pump ) . It gives me a mixed feeling. Although the pump is working fine as of now, it may need to be serviced after some time. But seller promise me to provide free repair(within 5 Years of purchase).. Thanks
