Just a small point, but the half-track on page 41 of your July issue is not as described. The shorter body shows it to be an M2 model, not an M3. Also, the lack of mine racks and pulpit gun mount show that it’s an early version, not an A1. Therefore, it is not an M3A1 Armoured Personnel Carriage.
From the angle of the photograph, it could be an M4 Mortar Motor Carriage but it is more likely to be an M2 Half-track Car. I hope this is helpful. Kind Regards,
