Off the top of my head the only one I can think of in current production is the Benelli SBEII. IIRC Rem made a 11-87 LH for a while and maybe a 1100?
I am sure there are others.
ETA, what is he planning on using it for? Geese and ducks - then see above (SBE). Anything else, I would look around for other options.
