Dr pepper machine

Hello, I have a selectivend machine model 3A.  It's a Dr. Pepper machine with the newer logo (not the 10 2 4 one)
it has a glass door on the right hand side and holds up to a 16oz bottle.
2 questions
1. any idea of the age or value of this machine? works great
2. where can I find soft drinks in glass bottles to fill the machine.  I tried the Mexican Cokes and got the runs when I drank them.. grin.

I sure miss popping the top off a soda and watching it turn to slush and push its way up the neck of the bottle...sigh
Thanks in advance.

Does it look simular to this SV4a ? if so it's a 60's shelf machine. I bought this one for around $75.00 working condition.light-up sign & bottle door,(it was Dr.Pepper mint green, a 7UP dealer repainted it white) this big guy isn't very much in demand (kinda big @ 76") if the 3A is smaller it'll fit in more peoples game rooms & basements! love to see a picture!
please post one!later...johnieG
