Trick lock 19

this one is really crazy..... see the style....... not normal to use so much tricks !

you have to unlock both slider bars

 
also open two hooks / brass decorated

both open two doors ;-////////   a lot of work !

for two different keys ! Each open one shackle two the left and right !

only all this work open both shackles
Can not believe this lock, It work very good but it need a long time to find out how it work.
Fun stuff... want to know what it was in use for !
