say I want to do a very large 1/76 HO scale train display. I have all the cars, people, houses, accessories, roads, etc in 1/76 scale. For me it’s very hard to find aircraft of most type, boats, and military vehicals/figurines/the whole 9 yards in 1:76 scale. So say I used 1/72 aircraft, boats, and military, do you think it Would mix well? I wish to have an airport and large military base, and maybe a boat dock, incase you were wondering. Lol thanks and I hope you reply!
