Looking forward to adding some of these to the hobby desk!
Recommendation in regards to decals, I believe "BEAUTIFUL QUEENIE" should be in white and if there are corresponding stripes to that vehicle they should be blue (based on other vehicles in 5TH Landing Vehicle Tractor Battalion). I've only seen the poor black and white photo of "BEAUTIFUL QUEENIE" which makes discerning color difficult however, there is original color footage of 5TH LVT Bn during Operation Detachment. 5TH LVT Bn was assigned Beaches Blue One and Blue Two, with the LVTs being painted accordingly. For the assault however, Beaches Blue One and Blue Two were deemed fouled or unusable and thus 5TH LVT Bn landed on alternate beaches.
3RD LVT Bn assigned Beach Green
5TH LVT Bn assigned Beaches Blue One and Blue Two
10TH LVT Bn assigned Beaches Yellow One and Yellow Two
11TH LVT Bn assigned Beaches Red One and Red Two
2ND Armored Amphibian Bn - individual companies were assigned to support LVT Battalions.
Markings, beach or unit were not consistent across units.
