David,
Here is one for you, 693027.
Notice the box number is 2 digits off the K22/40. I bought the box from a member earlier this year and the box was in Montana. I was walking the isles in Kansas City last month at the S&WCA annual meeting and looked on our Lee Jarrett's table and my heart skipped a beat when I saw the serial number and told him I would be right back. Went back and looked at my box, that i had brought with me, and WOW 2 digits off.
Next week I will have another post for you.
Regards
