Alright, I'll bite.

Do you have some knowledge of that specific rifle beyond what has been shown so far?

Aside from what may be a bit of sloppy workmanship at the upper band, I do not see anything overtly wrong with the wood. Of course, the absence of the proper rear sight is a very damning indicator.

Maybe the seller is making an innocent mistake, maybe not - in any event, perhaps a beginner's buying mistake will be averted. Looks like the seller did just enough "research" to see that 26" equals a high price to the uninformed.
