what an excelent base for a project ! i am green with envy ! is that a hole cut in the lower hull next to the rear bogey,or is it a trick of the light ? you are lucky the centre bulkhead and ducts appear unmolested. and you have some swanky looking sand guards too.....
looks like you will be riveting shortly then
do you have any details on the numbers lower tub / armour etc etc ?
