No harm bheston, I did the same when I purchased mine a few years ago. I received a call from my original owner after 3 weeks of emailing him. Come to find out that he was in the mountains out west and no way of checking his email. So hang in there..heck I'd try again after a few. Never know, may have went to spam or accidentally deleted.
I'm currently waiting for the possible second owner and the last of four to contact me. I'm 99.9% sure I've located him after 2 years of brief searching. Up until last week I had been searching for a girls name with no luck. So I took another approach and may have hit jack pot !!
Story to come if I'm correct
