I really wish people at Met would let me handle theirs.
I have seen the picture in Fernando's post, one appears to have the spring on top, that latches the bar in, the spring idea is also on the table at this time.
screws and pin fastenings were known and laboriously hand filed, as were small intricate gears in pre-christian greece/rome. common metal screws were 16c, contemporary with the sword. many wheel lock firearms used them, and accurate screw cutting lathes were invented late 18c.
there's a lot of ancient technology that was lost and we are still rediscovering it. like roman concrete used to build the coliseum and the pantheon, which sets underwater and gets stronger with age, not weaker like our 'modern' version. our's barely lasts a couple decades. the unreinforced dome of the pantheon in rome has lasted for almost 2000 years, having only needed some minor repairs in 200a.d. after a quake. we only recently found clay and bimetallic batteries we think were used in pre-christian turkey to electroplate stuff. and so it continues... the 'ancients' were just as smart and crafty as we are. and a lot more brutal.
you could always try the royal armoury at leeds, uk. they may have one they could photograph for you if you ask them nicely.
