Exactly, you can see the metalic luster on Rodericks and with some age darkening. So, which are you willing say is correct? Roderick's time capsule or your, non'metalic?
IMO Roderick's timing cover is the only 'real deal' displayed. You can see that the forward edges that have not received much heat are quite light colored. It looks as though someone changed the water pump and painted it with available early spray can paint.
