David and all: The best thing to do is to find the Merckx website...Merckx.be I think but any google search will find it.
Send them an email with the serial number and model and they will respond back with all the particulars. In my case they even shipped (Free I might add!!) a bottle of touch up paint for my Gran Prix. I was very impressed.
Good luck and welcome to the owners club.
Cheers,
