Mystery cattle brands

I'm hoping you can help the folks at Pechanga Cultural Resources identify some old cattle brands. (Their sketches are at the end of this post.) A large number of branding irons were
offered to the Temecula Museum, which accepted some of them -- But the rest were donated to Pechanga. They think they are Southern California brands, but don't really know from whence they originally came.
The photo above shows cowboys Nick Gonzales and Henry Serrano branding a calf on the Starr Ranch. The photo below shows cattle branding on the Rancho Mission Viejo in 1964. And now for the "mystery brands" themselves. (I've added a number next to each brand to hopefully simplify the process.) If you can identify any of these, please post the news here and also send the information to Teresa Lorden, Curator at the Pechanga Indian Reservation. Her phone number is (951) 308-9295.
