Can some one put a price on these classic airguns?

My neighbour wants to sell these rifles and wants to know who much he can expect to get for them.
The first one is a BSA Club .177 S/N E10527. Needs some repair work on the stock and it has had some repair work done to another part of the stock.
The second one is believed to be an Midland Gun Co. Demon. Production between 1919 to 1935. Needs some work and a replacement rear sight.
