first of welcome to the site
next,
thee answer is, NO< as over the 12 yrs of its life lots of things could have happened to it, and in today's world of scammers, and dishonest folks, you will never know the truth
I'm guessing you possibly thinking of buying this machine?
or a guess on my part
and as such, buying used equipment is more of a gamble now than ever
folks remove and replace things to alter readings, happens all the time, as well as folks doing other things, or never fixing things when a hour meter fails and just run it as is till????
best advice when looking at used equipment is, know what to look for, and or bring someone that does and even then its a gamble,as you cannot see the inside of parts no matter how skilled you are!
but more experience the better ,as many things can be seen if you know what to look for!
