100-1000 USD depending on specifics
Please ask a question. JM Brownings first patented pistol is the FN model 1900 patented on April 20, 1897 a .32 caliber automatic pistol.
You need to submit the kind of firearm is it? Pistol, rifle, shotgun?
The pistol is actually a Model of 1900 made by Fabrique Nationale (FN) and designed by Browning. These were used extensively during WWI by trench sweepers and Belgian/French officers. Modern repro magazines for them are available from gun parts sources (try numrich online). Good luck. FYI, Brevete means "patent" and SGDG stands for "Sans Guarantee Du Government," which means without the guarantee of the government. The name of the gun is FN Model 1900 or Browning "Old Model."
10-100 USD or so
A Lver Johnson model 1900 22 revolver gun can be worth $115 dollar or up. It all depends on the shape it is in.

50-100 or so
value depends on overall condition. the break open pistol stems from turn of the 1900's, and are not in the real collectible world......................
If you have the FN 1900, also called the Browning #1, it was produced from 1899-1907 and there were 700,000 made. It will have "Fabrique Nationale-Herstal-Belgique (Brownings Patent)" inascribed on the left side of the pistol. Under that it will have Fabrique Nationale's icon with a small picture of a pistol and a circle around it. Under that it will have " BREVETE-S.G.D.G." which is a french term for the patent process. It was used on many things including clocks. Hope this helps.
Good question- with no clear answer. First, Fanny Kaplan did not kill Lenin. He lived several years after the event in 1918. Secondly, it is now questioned whether she actually shot him- or if this was a staged event for political purposes. The firearm is question is referred to as a "Browning revolver". However, Browning did not make revolvers- they made automatic pistols. A likely candidate is a Browning 1900 or a Browning 1910 pistol. However, I have no definitive answer for the make, model or caliber of the gun supposedly used. Sorry.
