I have an MT with f holes, I purchased a few weeks ago used. I'm a newbie and am enjoying my Collings very much. It's slow going right now but I just love the feel on my lap and in my hands. I will post a pic tomorrow.
I just bought an MT -- sunburst with ivoroid binding, a gloss top and wide nut (1-3/4"). This mandolin was mint and I got it for $800 under street price by buying used. She sounds incredible, plays like butter and looks fantastic. I was pleasantly surprised and the brilliant shine on the englemann spruce top and the headstock is glossy, too! Collings puts the detail in the fit and finish. Wow!!
I am the second owner of a MT mandola. I love it. It is a cannon. I have no trouble being heard at jams when I want to be.
