Identifying ADALP2000 marking for zener 1N4735 and small signal diode 1N3064

I find it VERY difficult and frustrating that the parts for some of the diodes in the AALP2000 kit come together taped and there is no real way to identify which one is which.  If I zoom in the each part I read

PH C3V6    on one of the diodes and  ON J2 0 307 on the other

Which one is the zener 1N4735 and which one is the small signal diode 1N3064!

I Googled it and there wasnt a clear description of what these labels represent!
