Order the above to fix it yourself, or have a gunsmith do it. I've had it done on a Colt years ago, and it's still going strong.
You fill out a piece of paper, send a copy to the ATF and to your chief LEO wherever you live, and the ATF sends you a piece of paper that lets you buy old guns through the mail anytime you want. It also will get you a discount at a bunch of gun related places. It's pretty much a no-brainer, every one of us should have one.
This is just a suggestion, but get your C&R and buy one on gunbroker. Model 12s are available there all the time and you can get one in any condition you want. With a C&R you will not have to pay for a transfer and the C&R will basically pay for itself with that one purchase. Model 12s are basically all C&R because they haven't been made for over 50 years.
