Well I for one am sorry you feel that way. I was actually going to respond to your post, but I wasn't sure of what to say. I love martins, and yours is a mid 60's most likely (I have to check the serial # to be sure). The reason I didn't reply was that I wasn't sure how badly your horn was corroded, and didn't want to give you an answer that was incorrect for how badly or not your horn was in need of repair. And your not the only one who gets ignored. I have posted here before and gotten no response. One I post 1-2 weeks and no one else commented on it yet. Well I hope this helps a bit in why I at least didn't respond.
