Getting A C & R..
That had to be the easiest thing I have ever done with a government agency, especially a Federal agency. Mine took right around a month total, even with my screw-up of forgetting to include my local CLEO info on the form. There is a bad side to getting the license though, that $30.00 license is going to be harmful to your wallet for quite some time, as you are going to find countless firearms you just "have to buy." Getting one was kind of a necessary step for me, my hobby has become collecting vintage military surplus rifles. Some quite beautiful, some plain Jane's, but all with a sense of history in their cold steel and wooden stocks.
But welcome to the wonderful world of curio and relic firearms, if you need a few links to friendly information sources, or forums where other collectors frequent, let me know, I've found a lot of kindred spirits on-line that are very happy to share their knowledge with those just starting out.
