The same with Planet X. The guys name who built it etc is on the cert.
I too thought I'd be able to see it. But no, they said they hide it for security purposes. They also said the owner has to strip it therefore they are the only one who knows the number. I think this is nuts as they are assuming a degree of competency to do the job yourself, or advise taking it to a LBS for them to do it, of course you incur the cost here.
