Though this will not help the original poster.
Before our European tour last year I started researching step through touring frames for my wife. It seem that her hip gets aggravated in the on and off of her LHT. Used the site Cycling About. We bought a frame and fork, raw steel, in Rotterdam,Netherlands. Just finished the paint job and built it up with a Rohloff. Nice bike! Lots is selection in Europe & the UK.
