First off I did search but this is a little different.

Now that thats out of the way I have been here for about a year I guess, just reading and learning though. I just picked up an older Schwinn off of ebay for really cheap (about $25) and surprisingly its in great shape! The only thing is neither the previous owner nor I know what model it is. So here are some pictures, any help would be greatly appreciated.

Ohh and also any ideas as to where I can get some sealed bearing for the headtube, it had the loose ones in there when I got it. I didn't thing about it and took the fork off so I would rather not be faced with putting all of the balls back if thats an option.

Thanks in advance.
