Good stuff above ^
Just a couple of points. An FFL-01 (standard dealer), 02 (pawnbroker), or 07 (manufacturer of firearms) are all valid receiving FFLs for any firearm (C&R or modern) other than "Destructive Devices" (oddball category covered by the NFA). https://www.atf.gov/resource-center/fact-sheet/fact-sheet-federal-firearms-and-explosives-licenses-types
I was almost burned by the EZ check system by an online auction house whose employees didn't understand it (written right in the second paragraph on the site: "FFL eZ Check does not validate Type 03 (Collectors of Curios and Relics) and Type 06 (Manufacturer of Ammunition) licenses."). After not receiving the firearm or shipping info for an undue period of time, I contacted them and they said they were holding it because my license was invalid. I explained the law and the site to them and they finally figured it out and shipped it https://www.atfonline.gov/fflezcheck/
All FFL-01s I've dealt with require at least a DL or my FFL-03 for receiving. The FFL-03 is just an alternative form of ID, not required for shipping the C&R eligible firearm.
I've run into relatively few FFL-01s who won't accept an FFL-03, but they're definitely out there. In my post sale notification to a buyer, I always add some language to the effect of "make sure that your chosen FFL will accept shipment from a private individual or FFL-03 holder". My LGS is one of those. I like the owner in spite of that
He never charges for the background check on a firearm in the shop (that'd definitely be a deal breaker for me) and filling out the Form 4473 only adds five minutes for me and costs him the time of one of his employees to fill it out and call it in, so no big deal. Besides, the less he knows about C&Rs the better my likelihood of finding low priced ones in his shop
In addition, file under the "I don't get mad I get even" category
, I use an in home FFL-07 for receiving modern firearms partly due to his policy.
