MMMM, let's see... the nib is bent, the section looks like it was chewed on my someone's kid or cat, the clip is wrong. It appears to be a standard grade Third Generation.
Parting out the pen you are looking at about $40 I would say, maybe a bit more if the body is good...
IF you have the parts to correct the pen it might not be a bad deal at the asking price to about $25.00
UNLESS, it is one of the Vacumatic clones we sometimes see, then it might have some collectible value as a counterfeit.
But, what the hey do I know...
