Found this for sale. Sounded good until you look at the add. Yep you could have a lot of fun with it but exactly what part of it is 1912 ??
I see no actual 1912 parts other than the lamps and windshield. Still a great looking T.
He put an ad on the MTFCA classifieds earlier this week:
There are other examples of this omnibus body - there was a fellow who sold plans for it in the 1960s.
Two examples in this thread (one at the top and second one built by Dave Ferch much further down in the thread):
Another example in this thread:
Looks like a fun T to get others interested in the hobby by giving them rides. The interesting part is that the roof can be adjusted to fit in your garage.
Dave Ferch in Minneapolis built one from the same plans on a 1915 chassis. His son now owns the car.
You can see a picture further down in this thread (Northern Lights Article).
The original intention of the removable top is not necessarily so it will fit in the garage or a trailer. It's also so you can drive the car with the top off.
Also, the window panels in Dave's omnibus were removable so the omnibus can be driven with the top on but the windows off (this is how I usually saw the bus when Dave owned it, with the windows removed). The "1912" that is for sale probably also has removable window panels.
