...or Zirah Bouk.
See Artzi's examples ## 5886 and 7961.
Also, see one from the Met:
https://www.metmuseum.org/art/collection/search/31537 ( Stone's bequest).
Although Artzi, G.C. Stone and curators at Met are just the beginners, they are not so bad
The clue to identifying what was called Zirah Bouk is not in the T-spine, or blade form ( straight, recurved), but in massively swollen reinforced tip, just like in your first example. Its very function gives rise to its name: Zirah Bouk is Farsi " mail piercer". You can see Stone's book or Elgood's Glossary in his " Rajput arms and armour" and read how these "beginners" define it.
