1. MK
9. Master
I don't see any Jabos.
Possibly Akro on #3 and 5?
No idea on #7 ... I just don't see Jabo.
For #11, the V-shaped seam sort of makes me think of Master but at that size, in that glass type, I say no to Master. So my thoughts are Akro or modern, but wouldn't be surprised if someone else said Vitro or MK. Lots of help, eh?
