That is so awesome! Thank you for the help! I love these pieces of history!The yellow painting is someone's name followed by what looks like "113" possible a rack number. The name could be the person the rifle is issued, likely a militia member or high school/college kid attending military training. The top character is "Ying", the last name, the second and third characters are the first name, "Fengzhen". The name is more like a female name as both characters in the first name were normally in a girl's name. With very rare cases that a guy has a female name, very rare, but not impossible. No doubt there are females in militia unit, and among school kids received military training, but unlikely front line solider being female. Couldn't identify green paint characters.
