Something bothers me about it.
I still think that a useable CB450 gas tank and especially the emblems belong on an original bike and the entire bike should be on display, not in a case by itself.
It is like people that collect Gibson Les Paul guitars and hang them on the wall to rot,
while many musicians dream that they might be able to own one.
Now the wood for the guitar necks (ebony finger boards) is running out, and the guitar factories threw out many "2nd"s that they are sorry about now.
Right now is a time that because of the economy many people are rebuilding older cars ,motorcycles and may other things and give them a new life. They need these "vintage" parts before they become so expensive that getting any parts will be prohibitive.
