I, too, have the 2.25x3.25 Galvin with a stable of lenses. My initial reaction when I read your post was why you specifically want a normal focal length lens? Is this a compromise so you carry only a single lens with you? I'd think there'd be so much you'd want to capture on film that a wide angle and a long range lens would both be used.
When I travel on business I usually take my Seagull TLR because it has a fixed lens and I'm not tempted to carry too much, or I take my 2.25x3.25" Crown Graphic, which also has only the one lens. By eliminating lens choices I restrict what I put in the suitcase as well as the types of images I capture.
Enjoy the trip,
