That's a Gloria 'Bartali' lever as used by the great Italian - and lots of Bartali wannabees in the '50's. The projection is supposed to be for the rider to hook their first finger around to give more 'pull' when climbing etc.
It's actually a road frame as it does not have the rear facing rear 'dropouts' and looks quite a nice one.
Perhaps someone will recognise the frame number and the curved rear brake bridge is a possible clue.
Is that a centre-pull rear brake cable stop hanging from the seat binder bolt?
