Quick Meal Stove

i know this needs a lot of work......it's a winter project for me and i'm starting from absolute scratch. i'm having issues finding manuals, and also replacement parts for this. information is possibly out there, but is hiding rather well from me. the broiler opens with no problem, i think the hinge on the oven part is broke and needs replaced. i assume that explains the twine holding it shut. it appears stuff is missing in the stove part. considering i know nothing about how this should function, i have a lot of research to do to make this functional and if i cant find the parts, it will remain decoration until i come across the parts. ANY information on this is greatly appreciated and useful. i've had little luck online.
