The 315 is a 10 1/2 ligne, 15 jewel movement that is interchangeable with the 345 although this particular one may actually be a 3157 as it is a 17 jewel movement which is differentiated with having conical pivots. Parts of the 315 may also be interchangeable with the 344 , 347 & 3157 per the 1939 Material Catalogue. Mike B / Barry C have the initial production date as 1929 for this movement although i suspect this one may be from the early-mid 1930's. I'll add a 'dial off' photo at a later date.
Of course, after i posted this i saw Thojil's entry on the 3157! 
EDIT: And...now that i have the dial off, i seem to have a broken clutch lever? I am in need of a replacement if anyone has one??
Still here....
