Can anyone identify the markings "YB1AL" "YUILL"
 

as the tittle says... I am trying to identify the markings to find out who did what to a set of labbed props I have. one is "YB (maybe its a 3?)1AL" AND THEN "YU1LL"

Sorry, I put I in the title and 1 in the post for the second number. Honestly I don't know, it could be either. I'm guessing the first letter Y and maybe last letter L will be the indicators anyway?


If anyone recognizes those please let me know.

Thank you!
