new purchase speedster maybe

You will need to provide some photos of the car to assist in its identification. Sometimes its impossible to to identify, but a number of enthusiasts like myself have been collecting data/photos of various cars and their manufacturers so we might be able to do so if you submit some photos to this forum.
If it has round bumper grommets they differ to original 852 cars and a number of correct replicas which have the square style. The square shaped ones are reproduced and available from Metro Moulded Parts. They sell front and rear original square style bumper grommets

1.Thinking of buying a speedster replica and the owner doesnt know who the mfg was, is there any way I can find out who made the car
2 .Also the rear bumper grommets are torn and round not square like most i have seen, does anyone know where I can buy the round ones.. any help would be appreciated
