Possibly the most popular luxury pen of the vintage pen era was the Parker 51. This workhorse was sleek and nearly flawless in its performance. Our Parker 51 is a later model from the 1950s. It has a good working "pli-glass" ink sac that you squeeze to refill. Better known as an aerometric filler, it was one of many popular innovations the 51 brought to the market. Also great were its hooded section that covered an all-but leak proof inkfeed system. It might be difficult to see in the photo, but this is a very deep burgundy set. Light wear from use on the writing instruments. The matching pencil still works great with a click. Comes with spare .9mm lead and a potentially working eraser!
