Mark, i would definitely not bring test equipment! I think that would fire the imagination of v e r y few people. I think the 348 / 375 pair would be a winner. Have displayed a photo or 2 of them in real life use and remove the tube cover from the 375. Or skip the photos and have a mic and key plugged in. I think a "radio tent" is realistic, that's what my father told me about the desert training area in California desert circa 1942.
