Very interesting e-bay item.

Has been listed for sale several times, it's also on a T club web site here in OZ for $8000.00!
Just save the paint and throw another one under it and your good to go!
I love how they say in the listing that it's a good pattern. $2000 (current bid), plus whatever the material cost would be to reproduce it, and you'd still be left with a trailer very few people would be crazy enough to tow with a T. I'd rather just throw a tent in the bed of my pickup and head for the hills.
Now that is my new favorite Model T.
If I got it I would do the bare minimum to make it livable. I would love to live in it for a few months;) even seeing it in a museum would be fun!
That thing was for sale at last year's Long Beach T Swap Meet.
