Fastback - I like your tank! Nice to see an orange one. I'm planning to join you in celebrating an alternative to yellow...... and black...and red. Go orange!

It looks like the answer is...no, no-one has seen one like this!

Still a fine looking tank though.
good spot by 79x100 about the rear seam. I've been working on my '74 roadster tank, and it looks 100% like the other guys' tanks.
That front seam is really quite intriguing; it was done like that for a reason, and must have taken some effort.

I guess the best I can do is admire your tank, and share your curiosity!

B+Bogus,
maybe the recess is for a drivers side air bag?

Does this look familiar Debby?
