What is the value an Iver Johnson Model X 22 cal rifle 1931?

Sir, How did you determan that the model x, 22 was made in 31? My wife has her grandmothers,nice little accurate single shot. Hers has a 22xxx number on it. She would appreciate any info or where to go to find some info on the model x. Thank you John The Model X was only made from 1927 to 1932, and that rifle is close to the end of production so 1931 is a pretty good estimate. These rifles in excellent condition might get $150, but specimens in typical condition usually bring $80-$100. www.countrygunsmith.net
