K ; The wood has been refinished...it's as well covered in that heavy varnish the nrowegians used during refurb. The serial on the receiver is not german period applied , same goes for the proof next to it. Is there a lightening cut on the siderail below the woodline of the receiver , and a close pic of the G33/40 marking would tell a load.
The bolt is as well a crude non german post war renumber.
The barrel was pulled from another rifle for sure. The receiver if - a big if here - if it was a 33/40 receiver has been totally scrubbed and fake markings have been hand applied to include the fake G33/40 that has been applied to the receiver siderail.
Fake G33/40 sight hoods can and have been made from 98k hoods and will fool most at a glance. If this were mine I would break it up for parts and toss the barreled receiver in a scrap pile if the headspace is no good for a turning into a deer rifle.
