I filled out the paperwork for this last July. It can seem daunting but there aren't too many hoops. Join the Garand Collectors Association, a 1 year membership is 25$, consider this like your tax stamp (except that the turnaround is immediate). Go into a bank and get the paperwork notarized. Firearms related activity, a C&R license is acceptable and is what I used, you could also use your concealed carry card, and if you don't have those, a range membership should work. My only other piece of advice that I gathered from other forums is that while many Field Grade are often in good condition and functional rifles, if you aren't heading to Anniston to hand select one, it is better to go with Service Grade. Mine is a great condition 1943 Springfield. It took about one month for the paperwork to go through, a week to process, and a day or two to ship. I've been busy and am just getting around to taking apart her and cleaning her up.
