Small pin fire revolver.

[Carlsr]

I recently stumbled across this small pin fire revolver. There are no markings as to the manufacture. The only markings I can find are what looks to be an 11 or 77 stamped on part of the trigger. This number is also written on the inside of the grips on both sides. Anyone here have an idea as to the manufacturer, caliber and value? Seems to be in rather good condition.

I have looked at a gazillion pictures and only one that comes close is a Belgian made American Defender. They are larger than the one I have though. My gun dealer told me it may be a lefaux,probably not the correct spelling. Said he never saw one that small.
