Don Collins still makes elephant ivory grips. Google collinscraft. Contact Don and he'll get back with you. I've got a few sets of his ivory grips, and have been very satisfied with his work. He'll explain the legal issues with ivory. He includes a photocopy of the original importation documents. He buys old elephant tusks from back when it was still legal. The few makers left all use the same approach. They purchase tusks from old guys widows. They won't touch them unless the widow still has the documentation. Back in the 50s and 60s, many wealthy sportsman went to africa and shot an elephant. It wasn't un-PC then. A pair of tusks is worth big bucks if properly documented.
Nutmeg Sports won't touch S&W grips. Jim Alaimo the owner is a Colt man only. He's a very nice guy, but he only likes Colts. He used to come to all our gun shows, and is fascinating to talk to. Don Collins insists he taught Jim how to work in Ivory....just to keep the record straight.
I haven't ordered any ivory grips from Don in a long time now. I'm guessing his prices are between $400 and $500 for a pair. He does special orders, and you can get a much better grade of ivory if you're willing to pay for it. I once ordered a set of N frame Magna's out of bark ivory. Bark is the brown outer part of the tusk, and is more costly.
We'd worked out a deal and he brought them to a gun show. His wife kind of attacked him for wasting a good piece of bark on a S&W because she said no one would buy them, and he should have used them on a set for a Colt SAA. He took his abuse but finished up the grips without telling her who they were for, just let her think he was testing the S&W waters. He got to the show and put them in his display case that held the other high value grips. I was busy setting up our tables and it took a little while to get away and go visit with him.
I walked up, took one look and handed over the agreed price. He's a master craftsman and I had no doubt the grips were correct. He had other customers and I walked away. After a little while, his wife noticed the S&W grips were gone, so she asked him what happened to them. He then did the usual husband like thing and told her the first person that looked at them paid full price. All true, but he left out the little part about the pre-arranged sale. At least she didn't complain about it again!
You can find N frame elephant ivory grips at almost any large gun show. If you want or need aged ivory, just be prepared to pay for them. I've labored over sanding off some of the carving on one set I've got. They're Asian style ivory, probably Vietnam War era work. I'm not wild about dragons. They currently live on a 3 1/2" RM. Its problem is its one half of a consecutive set of RM #s. I guess the gun stays with its 6 1/2" brother, I really don't care about the ivories, except I realize the value.
