Expert help needed... Is this Jagstangstang legit?

[AgusAD]

Hi! First of all, thanks in advance for your advice.

I'm from Argentina, and we don't usually come across vintage offset guitars, so I'm having trouble determining the authenticity of an ad that popped up nearby.

This "Jagstang-stang" thing is supposed to be made of:

Body: MIJ Jagstang
Neck: Fender Mustang 1969 original.
Pickups: Lace Sensor Gold/Blue (aftermarket)

Do you think it's an original neck? What should I ask the seller if in doubt?

Pics!

Umpteenth time's a charm!

Neck looks legit, heel should have a stamp "8MTH68" where MTH is a 3 letter month abbreviation. A MIJ Jagstang body's neck pocket would maybe have a model code stamp (e.g. JS-66) and probably a red capital letter stamp like K.

Thanks man!
