Since getting to know Matt last year we decided to team up and launch the group Celtic Signatures, all customers can be assured that when buying from Matt they will receive top service.

Matt is a credit to the hobby, I've gone from being a casual customer of his many years ago - to a working partner with Celtic Signatures. With Matt you can buy with complete confidence that the items you buy are legitimate and that he will act as upfront and honest possible in any transaction. A credit to the racc community.
