$700 would be high in my opinion based on the photo’s.
I’ve been second highest bidder for 3 rifles of similar or better condition and all ended in the $500 range.
One I bid up to $800 was 95%? Other than some recent orange rust it looked like the rifle was made last week. Crisp stock markings, rich nitre blue, etc.
So, point being, $700 sounds high to me, even if it had a mint bore.
