Sorry for the poor quality photo. It's a copy of a 35mm slide. I built the 1/72nd (Revell I think) kit 40 or 50 years ago. The scene depicts bore-sighting the guns. The crewmen are Airfix, some cut apart and repositioned. The bore-sighting equipment was scratch built, as was the 'in the field' hoist. Oil stains are thinned India ink. The 'sand/dirt' is baked flour. I think the most expensive part was the tiny chain on the hoist! Yes, this was a labor of love. I don't think my eyes are up to it today! Ole Bill
