Trawling through dozens of old boxes recently I stumbled across a small box of these. We had a good range of different sized flat steel blanks going back but from memory most had the generic round or trefoil bows, mostly for cabinet and drawer locks etc, so a bit unexpected to find these Yale Junior and Willen Blanks for the old Spring night latches.

Does anyone know what the smaller ones at top left in photo 2 are for? They seem that bit too small for the latches, the whole bag are unmarked except for one which is strangely stamped 'Made in USA' with 842, of which the numbers are each different sizes! And, 2484 on the reverse of the bow, which is the total opposite being very small and precisely stamped perfectly central.
