Mark,
I believe the case shape should be tonneau, as indicated by the dial and crystal specs. The case should be ever so slightly curved down the sides.
The Minute Man should take the following crystals measuring 26.7x16.5:
BB MT2675
Perfit MB267/2
GS MT366-10
Federal MT4-265

Darren, if you look at the outer minutes chapter they are slightly curved outwards, and the case shape follows. Shows up best in the first and last pics.

I don't disagree with the Mark's id, I'm just trying to "nudge" him into correcting the case shape in his details.
Great watch. Nice band. Keep 'em coming. Confirmed ID from me.
Thanks Will,
I'm liking the era strap also.
Darren,
I'm not so sure this Case shape qualifies as 'Tonneau' ? but I guess if the Crystal is MT then it must be?

The Glass going in is a Federal: MT4-265 165

"MT" in all of the crystal part #'s indicates "Military Tonneau". Your last pic says it all. I'm sure that if you put a straight edge down the inside of the bezel it will be slightly curved.

era strap- It looks identical to the strap in the ad. It's great to get the complete watch in this shape!
MT stands for Military Tonneau, shape of the glass, and case.
WOW what a watch. Where can I get one ?? It is just as flawless as your other examples of beauty and I am getting green with envy.
Great find Mark.
