Hello All, I need some help from some of our Oriental pen manufacturer gurus. I recently acquired a NOS fountain pen from one of my contacts in China. Unfortunately, sometimes the language barrier gets in the way. I bought a beautiful aerometric fountain pen circa 1997. Its a Chinese/Hong Kong event pen. I can find no Stamps other than 9771, two Chinese characters on the central band, and a very small almost undecipherable logo on the pocket clip. Both Wing Sung and Hero used the Chinese characters sometimes instead of their logos. So what do you all think? Is it Wing Sung, Hero, or another brand? Thanks in advance for your help. 😊 Uther
