This is a Hero black with metal cap cartridge fountain pen, possibly a model 440 variant, date unknown. The pen is similar in build to the Parker 45 and uses Parker type cartridges. The front of the cap is stamped with the Hero name in Chinese and the back is stamped MADE IN CHINA. The spring loaded clip is stamped HERO. The cap has CHINA – USA over Friendship marked on the front below the clip and characters on the back. There are no markings on the cap and barrel. The section has a gold painted ridge decoration and this section type also appears on Hero 121, 121A, 240, and 440 models. The nib appears to be stainless steel and is stamped with the Hero name. The plastic barrel is dished on the end as is the cap top. #pencollecting #fountainpen #hero #heropen #shanghaihero #shanghai #parker #parkerpen #penhero https://www.instagram.com/p/CD7CjpNjQ7N/?igshid=1h5hkipyvxfs7
