Sightglass is missing and appears someone has tried to repair and perhaps sealed up holes. I do not know if it is air tight but no doubt needs to be restored. As can be seen engine is a little over 12in height. Rest assured that model will be packed very carefully.
Can not guarantee against damage but close to it. I know how frustrating it is to receive an antique such as this damaged from careless packaging.
