Mark,
Welcome to the Forum

First you do realize this Forum is not part of Smith and Wesson. The Forum is privately run and has no connection to the manufacturer of firearms.

You also posted this in the Smith & Wesson Historical Foundation section. The Foundation also has no connection to the manufacturer of firearms and nothing to do with your letter

You requested the letter from the Smith and Wesson Factory.

Usually a Factory Letter takes 12-16 weeks. You only had your check cashed 3 weeks ago. Nothing is even close to being late yet.

However the Factory Historian (yes there is only one person that does this job) is on vacation and doing some shows so he will not be working on letters for the next 4-6 weeks. This is probably why the Factory disabled the letter request page on the Factory site.

While you could call the Factory, all they are going to tell you is that your request is in the queue. They can not possibly give you an estimate as to when you are going to get your letter.

Just be patient and try not to think about it. It will get there
