Congratulations on the beautiful new guitar.
The man who can tell you the exact date it was made is Jim. As you probably know, Avalon stopped building guitars earlier this year and the workers were laid off, including JIm, but he does appear here still.
In the meantime I believe your guitar was made in the Newtownards factory in Northern Ireland in 2005 or 2006. The specs would be:
Solid cedar top
Solid rosewood back and sides
Ebony Fingerboard with Mother of Pearl Inlay
One Piece Mahogany Neck
Tusq Saddle and Nut
Gold Grover Tuners with Ebony Machine Heads
Hand-Buffed Gloss Finish
I hope this helps until Jim can give you confirmation of the year it was built.
