It's a nice looking roadster. Not particularly old or worth much money, but it'll be great for trips to the shops or going to work.
You'd be able to make an educated guess at its age by looking at the back wheel if you still have it. The hub will have a date stamp.
If not, Freemans Cycles could build you a back wheel. Most shops won't have this size though.
Other than that, show us it when you've done it up!
