Bikes with some chrome showing were usually fully chromed; the chrome under the paint was not polished so the paint would stick better. In your case, the entire fork was chromed but only half painted.
If the components are still on the bike, you should be able to clean them up and reuse them. If some are broken, I'd look on eBay for a replacement. We can help you with identifying parts and give suggestions on repairs.
It would be of great help if you'd take lots of good quality pictures of the bike and the components and post them here.
