Not to jump in on this thread but a couple months ago i ran into one of these shotguns in grade 2 in very nice condition case hardening visable with 24 in. barrels that dont appear to have been cut [???] also the Damascus barrels are in exc. cond. inside and out. the pistol grip bottom is flat. I located a second set of steel barrels which I am fitting. also automatic ejectors serial#26432 I didn't know if you are collecting info. if so i hope this is helpful.
regards
