Anyone have a "Goose Neck" Rivet Gun available?

Hi, I’m in need of a classic old “Goose Neck” style of rivet gun. Frustratingly I used to have a couple but donated them to a museum some years ago. Now I need one again to, well, drive some rivets back into an old aeroplane! If anyone has one kicking around a shed, tool box or whatever and which they may part with please let me know.

Also interested in and needing “Bucking bars”, particularly with a narrow head for use within stringer sections.

Thank you
