ducks..also it should say August Francotte maker & patentee liege Belgium on bottom of both sides of side plates. It should also look pretty damn nice, with perhaps nicely carved fences, decent wood, even though the 20e was the lowest of their side plated BLocks, a quality gun, I have had a couple of them, & a 25e. Great looking guns.
You can look in the Other Useful Information at page bottom for dating by the serial # hope its a good condition gun
cheers
