Restore it if you like,I prefer them unrestored is all.Ill post some pics of one of mine,I have one identical to yours and another later one which has its rear flap only,it can stay in storage untill i get the other bits,along with half of my collection since ive got so many going already.I fully strpped my early one cleaned tidied and replaced anything broken,rebuilt the engine with gen parts and left it at that.actually just need to fit the starter knob and its all done.
