This is a lovely Parker 51 fountain pen which comprises a Black barrel and Steel cap. It dates from the 1950's, is 13.8cm long and is an aerometric filler.There are no barrel imprints and the hooded 14K nib has a Medium tip. The cap has the usual arrow clip with pearl screw and the Parker name can be found near to the mouth of the cap. The pen is in really lovely condition, pretty much Mint. The plastic has no cracks, scratches or dings and no surface wear. The cap is excellent with no dings and the nib is beautiful. The pen is in working order. It fills easily (unscrew the barrel and depress the pressure bar), holds a good quantity of ink and writes very nicely. This is the nicest Parker 51 I have seen for some time - no sign of use apart from being inked. It would enhance any collection or, of course, is ideal for daily use. The buyer is sure to be delighted with it but, as always, a full refund will be offered if he/she is not completely satisfied with the purchase. Buyer pays postage and packing. To addresses in the UK the cost is £4.50 (Recorded delivery). To addresses in the USA and Europe it is £8.50 (International Signed For). Buyers from other countries please contact me for prices.
