Welcome to the Bicycle Forums Scott.

The Galaxy is a popular collectible vintage road bicycle. I know nothing of the other two.

Generally, when asking questions or seeking information on the Bicycle Forums, it is wise to include good clear pictures of what you are interested in.

As a bit of help to people, new to the interest of vintage bicycles, I publish MY "TEN SPEEDS", a website intended to help people learn, quickly, about vintage bicycles and, hopefully, help them to avoid the mistakes I made while learning.

Hope this is a help.
