I have one of these but mine does not have the bound headstock. Other than that it is pretty much a clone of yours. Mine is a D serial number also. It was my first Heritage. I bought an H-140 of the same vintage along with the H-170 and fell in love. The music store didn't know anything about Heritage and I traded a japanese LP and maybe $400 for both. The H-170 is my favorite guitar. Period. I have a few Heritage's as well as the usual suspects (Gibsons, Fenders, etc) but the 170 just feels and sounds right to me in every way possible. The Schallers were not awful but I put a set of Dimarzio Anniversary PAFs and it just opened it up. Same with the H-140.
Everyone who has played it instantly falls in love with it and wants to buy it.
Enjoy it Brent!
