Excellent Find, Fred!
That's possibly the most beautiful 700 Special I've ever seen, especially with the original Special bag, cord, and plug in great shape! And I can see how the more modern attachments and Veriflex hose came with it, as they were the current attachment style at the time of rebuild, and were also sold with the 29, 62, and 115.
I have the same 700 Special, but mine isn't nearly as nice as yours. Mine has the usual battle scars, a really short replacement cord, and although I do have the original bag, I have a replacement on it now as the original is in dire need of repair.
Congrats on a great find,
Jeff
