Hello, Just to let you know cddstamps - by popular request - has started listing our stock in our online store with both Scott and SG catalogue references.
We just listed over 350 GB Machins all with Scott numbers. Perhaps you will find what you are looking for much easier now, if you want to fill a few gaps in your collection.
Or, you can search by value just type the face value of the stamp eg 9p and you will find all listings for the 9p Machins, both Scott and SG.
Sorry but we cannot ( well at the moment) back load Scott numbers for the 2000 plus Machins we have in the store.
Enjoy your collecting Michael cddstamps.com or go direct to the store by copying this link https://www.hipstamp.com/store/cddstamps
