Remington never made a "improved" model 8, unless it's called the Model 81 (an improved version of the model 8) however this gun was never (and couldn't be) offered in a 22, it's a center-fire rifle only. Either you have mis-identified what you have or the amount of gun-smithing done is substantial and like amazing if it works.
