Hero Model 616 Fountain Pen
The Hero 616 is a pretty good imitation of the Parker 51. I bought this pen new in 2012 and it was inked once. This black pen has a stainless steel cap (note the Parker style clip) and measures 5 3/8 inches capped. It has an aerometric filling system which operates properly and the plyglass is clear. The nib is a fine and writes smoothly. This pen is in beautiful condition.
