How about this one - work needed at the breech , and the foresight could be a replacement, but apart from that looks in OK original condition.

Shame there is no serial no, otherwise I can't tell if that is LincolnJ H model or an early BSA. I believe they changed the breech tap retaining plate from serial 2626, improved mod variant from then on.
BSA through breech tap retaining screw was bigger so this does not look original unless it is a Lincoln Jeffries variant of some sort. It would be hard to find a tap that would fit that early rifle well if the tap isn't the original one.
If it was the H mod then it would be worth a punt. Does look like a nice project for someone to restore that lady to its former glory.

The auction house could provide you with the serial number very quickly. As for the breech screw and small keeper screw, you would probably need to buy pattern parts from JK, or Chambers, then fettle them to fit. They would need to be distressed, but once done would be in keeping with the rest of the gun. You would probably need to do the same with the foresight, however once all that was done I think you would have a nice thing. Of course, The airsporter is purely an extra, and could be later sold to subsidise another Lincoln when the time was right. Whats not to like ?
