60 caliber Chinese wall gun cartridge by Tientsin Arsenal

The cartridge books by Logan and Huon depict the headstamp of the Chinese 60 caliber rampart or wall gun cartridge produced, I believe, by Tientsin Arsenal but do not give a character-by-character rendering into a Western language. Assuming that the drawings provided by Logan and Huon in their respective books are correct, could someone render the markings into English for me? If I have made a request more easily sought than provided my apologies in advance. JG
