I've discovered a major problem with this kit. When I compared it to the Tamiya large field kitchen, I found that the IBG kit is almost the same size! I know that the Tamiya kitchen is close to the correct size and that the small kitchen was much smaller, not only in size but also in the amount of food that it could cook. I don't have measurements for the small kitchen yet, but it is obvious from photos that it was much smaller. I will finish building this kit but it is disappointing to find lots of accuracy issues, apart from the size.
Scale large kitchen dimensions
38 mm wide 36.57mm long
IBG kit
37.17mm wide 37.89mm long
Tamiya kit
38.89mm wide 36.95mm long
I've finished cleaning up the chassis parts now, I hope to glue them tomorrow.
