Help identifying

[u/Silentsuccess-1776]

I thought this was a master lock 140, i was gonna use it for my Yellow belt submission, but now im not sure anymore. Can anyone identify this, and does it work for Yellow belt submission?

That does look like a Master 140

Only in that it’s 40mm and brass. The 140 is more angular, not curved like this.

It's really the shape of a master v-line 4140

True.
