Value of any gun is based on condition. And the old saying is "You're not holding the gun close enough to the computer to tell." The Forehand revolvers had a long history, modest collector interest, and prices (for most) remain fairly low. Link below will take you to some information on the company, and some photos.

The actual markings should read "forehand model of 1901". this revolver was manufactured by hopkins & allen co. between 1901 and 1917. 1917 is the year H&A went out of business and marlin took over the H&A factory to manufracture material for WWI.The 'forehand model of 1901' was offered as a 5 shot 32 S&W (small frame) or a 5 shot 38 S&W (large frame). standard barrel length for small frame is 3 inches and for the large frame 3 1/4 inches. These revolvers were manufactured for black powder cartridge pressures only and should not be fired with modern ammo. The low serial number and the F&W grips would indicate this is an early production model using left over parts actually manufactured by forehand arms co. before the H&A take over.
I just got one at a gun show, 50% bluing mechanically perfact, bore clean with crisp rifiling for grips totally intact $100.

i also own a Hopkins & Allen single shot break open shotgun with "Forehand" inscribed on its side and i recently learned from another forum that Forehand was another gun manufacturing company that was taken over by Hopkins and Allen from 1901-1902. Hopkins and Allen continued to put Forehand on their models until 1903. therefore the gun you own is dated somewhere between 1901-1903.
It would just be called a Forehand Arms Single Shot.
Anywhere from $10-$200, depending on condition, model, etc.
