The photo was originally posted back on the other message board, when I asked Robert K Weiss about any surviving Bluesmobiles.
On a side note...
With all the "upgrades" that were performed over there, the search function sucks just as much as always. I literally searched for an hour for the thread that he was posting in... with no results. It seems the whole system over there is screwed up. For example, when I do a simple search for my own posts, it states that I have a little over 50 posts.
"RKWeiss" has 14 posts but the system can only find one of them.
Anyway... I did save his comments in my own notes at the time:
March of 2010
Quote from Mr. Weiss:
The question was regarding any surviving Blumos (the productions shorthand for Bluesmobiles). These cars (as all in the picture) were constantly being rebuilt. There were different cars for different kinds of driving (high performance/speed, unfinished freeway flip back, etc.).
Many survived but I have no idea what became of them. We did give one away, as part of a radio promotion. Attached are a couple of photos Dan Aykroyd took during his creation tour of the Blues Brothers film story. They are part of the inspiration for the Bluesmobile.
