A couple of excerpt of the history of the 22-3000, taken from Jim Carmichael's book - The Modern Rifle, pg 214.
"The 2-R Lovell, sometimes called the 22/3000 , is in fact a wildcat based on another wildcat. The first version, called the 22/3000, was the 25/20 case necked down to .22 caliber. This made possible a velocity of 3000 fps. Next, an "improved" version was made by enlarging the chamber and fire forming the case to greater capacity. With a 45 grain Hornet bullet velocities of close to 3400 fps were possible. The Renowned New York gunsmithing firm of Griffin & Howe made quite a few rifles in this chambering and converted many others."
I have no idea of the value of the one that the OP is speaking of but I would think that if it were a G & H converted one, and was marked as such, that it may have a value greater than a donor action.
