Curl points out a very important detail of vintage rifle condition.
Although you can get into a BPE rifle that's had issues in the head and wrist of the stock -- if you're paying anywhere near top dollar it's very very important to make double damn sure that this critical area of the rifle is fit and original.

It is possible to have had repair/work in the head and wrist of the stock and have a perfectly functional rifle that will continue to function for generations, BUT tip-top original condition is just that - and that's where top dollar belongs.
Don't forget bore condition, *original chambers*, solid ribs and joining, locks inside-out, pins, finish...
All the way down to performance on target.

That pair of rifles definitely looks cool. I'd want to have quite the holiday with them, from stem-to-stern inspection to a good firing evaluation on paper before I committed to any price.
Can you get more photos?
Will the seller negotiate on the price?
Are they calibers that you'd want to hunt with? (I would!!)
Is that case original to the rifles - and are they valuing it at many dollars in the price?
Are there accessories?

Something else I've done with old guns and rifles that I've wanted to own and shoot is 'nondestructive inspection' including X-Ray imaging.
