Hi there, i have to agree, they def look like L333's to me. I have a trio that look exactly like that.

From looking at the pics, i would say ( i am no expert, but did manage to sex mine correctly)
pic 1 = the one that is towards the bottom right is a male
pic 2 = female, owing to the shorter ...

Could someone please help i have just bought a great plec, but i am not sure what it is?
