Test Eagle Serial Number--Duplicate

[sck]

Dear Folks: First, let me say that I'm new here and can't tell you how much I appreciate all the great information that I've already found. My question of the moment is with regard to Mr. Wood's comments about there being no possibility of duplicate numbers. I'm considering purchasing a reported test eagle, sn 6671, but there are a couple of problems. The toggle and trigger number do not match for one thing. In addition, the seller has told me that test eagle 6671 appears in Still's book, but that isn't the one he has for sale. As you can imagine, I'm a little reluctant to complete the purchase and was hoping for some advise. Thank you for your time and advice -- Steve
