Yes, the one that comes to mind was a mid 80s Trek 720 touring bike. I hit some ice and stuffed the front end into a 'two man' rock that was sitting beside the path. I buckled the DT so I thought I would cut it up and see what was inside! I can't find the picture ATM but one chainstay was half full of brass from the dropout end... I assumed the brazer was trying to show how much he was doing based on how much brass he used instead of units produced.
