Grandma's Pistol

Hello world.  Long time no see.  The good news is my PhD should be complete within a month (knock on wood).  For the past 6 months I haven't really had a spare moment.  But now I have a quandry for the masses out there that know so much more than I.

My husband and I are down to visit family for the holidays and were talking firearms and such, as you do.  This afternoon, grandma brought down this little guy for us to check out.  It was brought back from Belgium by my grandfather after WWII.  She doesn't remember ever firing it.  She much prefers her .22

I'm hoping y'all can help us ID this little guy.  It's simply gorgeous!

No serial number we could find.  The markings say A. Francotte a Liege.  Which matches with origins in Belgium, but my googling is finding my mostly long guns and a few larger revolvers by Francotte.  Heck, I'm not even finding dates they manufactured.  Definite search failure for me.

So, can anyone tell us more about this little gun?  It's about 3.5 inches long, folding trigger, pearl grips...  I'll let you see the rest in the pictures.  Not the best, but it gives the basics.  I can take more or different pictures if they would be helpful.
