Yep, sounds like a 03 FFL C&R License (which I have). You can buy and have guns shipped directly to you. Keep in mind though, you are not going to be able to get an AR or any other modern firearm with it. Just firearms 50 plus years old and listed as a Curio or Relic on the ATF list. This is a COLLECTORS license. For example, if a guy in AZ has a Win M94 made in 1934 or a guy in CO has an M1 Garand made in 1944, or a dealer in OH has a British No4 Enfield, you can send them the money and a copy of your 03 FFL and they can send the gun directly to your house. No need to use a Dealer as middle man.
You will also have to keep a book and log in/out any aquisitions and dispositions as well as subject to an inspection by ATF. No big thing really. One other advantage of having one is sending a copy to a lot of venders (Midway and Brownells for example)and getting the dealer prices on items.
