Good structural condition my friend repaired on the down tube which you can see. He’s been working as repairing fiberglass boats for 20 years! I have been riding it 3 years after his repairs. I was going to repaint it but decided to leave it alone. Cane creek headset just needs bottom bearing race for the fork. Any questions please ask me. Thanks.
