This Francotte is not the one described in the Von Lengerke & Detmold records for that serial number. This one appears to have been the one sold at the Christie's auction in London in December 1999. Here is their description.
"Lot Description

The treble-grip action-body with concealed third-bite, articulated front trigger, best bouquet and scroll engraving, bright cyanide-hardened finish overall, finely-figured stock, the barrels with matt game-rib
Saleroom Notice
This Lot has a manual safety"
I'll check this morning to see if we have the catalog from that auction which would include a photograph.
This Francotte appears to be a quality gun but it does not have the patina or characteristics of a 1920 Francotte. A photo of the proof marks showing the Belgian date code letter will help to determine its age.
