That is a great find, Sir!
Is the plate for account No. 8 missing in your copy? The account, titled 'a dogfight', describes an air fight in September, 1937, over Shansi, in which a Japanese maj. Miwa was killed.
If you have the plate for No. 8, it would be great if you could post it up. The markings of Maj. Miwa's machine are a subject of some interests, and while the painting could hardly be taken as definitive, it might contain some hint. Some of the depictions of the machines in those paintings show some accuracy in detail.
A good account of that fight can be found here, by the way:

"Seven Curtiss Hawk IIs from the 28th PS, 3rd PG were scrambled at 14:00 to intercept the IJAAF raiders. Captain Chan Kee-Wong, commander of the 28th PS, flying Hawk II No.7 from the Academy, led them. The IJAAF fighters arrived before the Chinese Hawks were able to climb to altitude. Diving into the attack, the IJAAF fighters scattered the Chinese Hawks. Lieutenant Liang Ting-Yuan in Hawk no. 2810 was shot down and killed. Lieutenant Louie Yim-Qun’s guns jammed and he had to retire from the action.
"Captain Chan found himself all alone facing three IJAAF Ki-10s led by Major Miwa. In what appeared to a challenge to "single combat", Miwa apparently ordered his wingmen to circle above while he took on Chan alone. Chan saw Miwa dive at him from above. Chan countered by pulling his nose up to face Miwa head-on. Anticipating that Miwa would need to pull out of his dive after they pass each other, Chan pulled into a tight chandelle. He was into his manoeuvre even before Miwa passed him head-on. As a result, Chan was able get turned around and was above and behind Miwa when he began to pull out of his dive. Taking advantage of his position for a zero-deflection shooting pass, Chan shot up Miwa's Ki-10, sending it crashing into a field near Ta Meng. Miwa was pulled from the wreckage alive but later died of his injuries.
"After seeing their flight leader downed, the two remaining Ki-10s dived into the attack. Without a wingman to cover him, Chan was put at a big disadvantage. Chan fought desperately to hold off the two Ki-10s, which were co-ordinating their attacks. After a series of frenzied turns, Chan found that he had lost a lot of altitude and running out of room to manoeuvre. In an attempt to shake his pursuers, Chan headed for the walls of Tai Yuan. Chan had hoped that ground fire from the Tai Yuan defenders would help drive off the IJAAF fighters. However, as he passed, Chan saw that the defensive positions on Tai Yuan's walls were empty. The defenders had probably taken cover when they saw what appeared to be three aircraft in a diving pass at them. Chan led the two Ki-10s in a mad dash above the rooftops of Tai Yuan, dodging around the smokestacks of the industrial city. Finally, the inevitable happened. Turning to avoid one of the Ki-10s, Chan was caught from behind by the gunfire of the other. Raking across the Hawk's unarmored seat from behind, two bullets hit Chan, one in the small of his back and the other in his left elbow. Chan recalled that his left arm "went cold" and he began to feel faint. Fearing that he would go into shock and lose control, Chan quickly looked for a place to land. He made for the playing fields of the Tai Yuan Women's High School, but could not clear one of the school buildings that was in the way. The stricken Hawk II crashed into the roof of the building causing Chan further injuries. Pulled from the wreckage gravely injured, Chan was evacuated to the rear. Doctors from the famous American-run Hsiang-Ya Hospital in Hunan were able to save Chan’s arm but his flying career was over."
