It is perfectly normal.  The serial is stamped into the bare wood, before grain-filler and the nitrocellulose is applied.   So you are good to go.

would it be a problem if I ask you if the below one is legit as well? The owner says it has the documents (even though the serial is not in the headstock). SN should be 132000534

what do you think?

 

Thanks!
