 The most refined of the Kristi snowcats was the KT7, which was last produced and the least successful commercially with only 4 units built and 3 of them were prototypes that failed.The KT7 was designed and produced after the sale of the company and after it moved to Washington.It is possible that additional KT2, KT3 and KT4 units were manufactured by the new owners in Washington state but it is unlikely since the designs had not been substantially upgraded by the time the new owners purchased the company.
