The second pen is the Gama Revolution with a Jowo 1.1 mm stub nib. This is inked with a Chinese Blue-Black ink of the GZ Boss brand.
From what I could find, this ink is made by the Guizhou Boss Enterprise (Guiyang Boss Chemical Industry Co., Ltd.).
They make two types of inks - LaoBan & Yingkesi. Based on the description I found online, I believe this is the Yingkesi blue-black fragrant ink.
