I just purchased a small Matchbox collection from an estate auction. These cars were owned by a model builder, and never played with. Some of these cars have been slightly customized by the previous owner. Some are mint and untouched, but some have slight additions, such as painted tail lights, or trim. I am not a Matchbox collector, so it's hard for me to tell what is factory, and what has been added, as it was done with great precision. I'm sure the paint can be removed safely, but that's for the new owner to decide. Just check the photos for condition.
