I'm not going to...

Can you tell me what/where to look to figure out why the breech isn't closing under spring pressure??? I can't even find a cutaway view of a 1900 to see how the mainspring fits...

ETA: My favorite auction house has a manual for a 1900 Swiss with a good pic of the fold-out from the manual (which they estimate will fetch $700 - $1200)...

Anyone know the most likely spot for problems??? I'm hoping it's something simple...Like the mainspring not being seated in the grip bottom...
