Peculiar posts inside Lachenal action

[Alex West]

I recently got this 1879 Lachenal in for tuning.  Inside the action are a series of small posts, dotted around the edge of the action and in between the buttons.  They look original and sit below the level of the action frame sides so aren't tall enough to support the fretwork - possibly they were there to support baffles? 

 

I've not seen anything like them before.  Does anyone have any clues?

It does look like there used to be a sheet of leather or something glued to the tops of the outer ones. Seems like it would make action maintenance more difficult compared to the usual method of gluing the leather to dots of cork on the underside of the fretwork.

Yes Dave, it's metal ended

not easy to confidently and securely attach baffles under a metal end, especially with older glue types
