Hello! New Guilder here

[adorshki]

So we have some series of letters that appears to be official. And then the "2 of 3". Wonder what that's about. 2nd of 3 models shipped to Thomann on Sept 29th?

I'd say that's 99.9% likely. The bar code labels are used to track a specific shipment and maybe even a specific package of a multi-piece shipment as it travels through the carrier's system.
Congrats and welcome aboard!

Man, I love those boxes. What a rush! Getting a knife and cutting the tape...First sight of the case poking out...Freeing the case from the box...The unmistakable sound of the latches being opened...Prying open the top, and...Oh, man! They truly are works of art. Congratulations! Neal
