I also have a pendant with "333 and a triangle" on the back of the bail. The pendant if triangular with two yellow bars coming down the front with a pearl betweeen. I understand the 333 is a German mark for 8kt gold but dont know about the triangle.

The Triangle might be an IMPORT Mark.
If, for some reason, you are unable to photograph the markings, Good Light & a Jeweler's Loupe might just be the thing to help you see the other markings that you mentioned, you can't read.
Happy Hunting!
