I doubled checked and the cost is $100.00. As I understand it the letter may include all references to the guns number any time it was in the factory.Are they $100 now? Still worth it if you have that special S&W. I've got a very special model 66 lettered.
I had gotten interested in the King modified Smith 1917. I was told that the letter would only include when shipped to the government. There was a world of information on King modified guns. I'll pass on a letter for that 1917. There are still two others.I be saving up for a letter.
I'm no collector but do end up with unusual Smiths from time to time. If you like high condition vintage Smith&Wesson check out the photos on the Smith&Wesson forum.
