Searching the FAA database on the N-number in the ad, I see that it reports the exact serial number you cite. So that record is straight.

As for the ad reporting the serial number as 177, that could be a simple typo on 107, which is likely the part of the serial number that represents the aircraft's position in the production sequence.

That makes sense - thanks, Bob!
On my glider, the serial numbers of the fuselage, three wings and tail are all different and got put together under A/C serial # 228.

Uli, but I believe the registration is based on your fuselage SN# . I have documents for a Libelle where the original fuselage was damaged and was swapped out with an earlier fuselage (earlier construction technique use with less glass)and the repair station swapped out the SN# placard with the later fuselage.. Now that was just wrong!
