I would simply clean the Alan and enjoy it. maybe get the decal that was used at the top of the seat tube and put it on the bottom area of the DT. now the fork....
as for Coicc, I kind of agree any damage may be very slight. if you have fork install it then measure the wheel base and angles and use the straight edge on the headtube /fork to see if it looks straight. I don't know what you have into it but I am sure some other C&V might give a few schekles for it
