I recently came across a pair of vintage skis, and when I started researching them I found that there is very little information about them even though they were manufactured by a major ski company with a major professional skiers name on them. What I have found are some Northland USA 'Stein Eriksen' L-21s. I have emailed a vintage ski shop about them and was not provided with additional information but was told they are valued at $250+, however they also had an interest in purchasing the skis as well. I also emailed some ski museums across the country and they were quite as stumped as me. The Colorado Snowsports Museum told me the following.."I would date these skis to after 1968. Maybe even circa 1975. All examples of the 1968 L-21 skis in our collection are paler in color and do not have the same logos/black stripe as yours. It seems as though this ski is a later version of the L-21, but I find it funny that there is no additional number or information online about later releases of L-21s. Maybe it is a special edition ski from the same time?" So I am wondering if I may have something special here. What also makes these skis interesting is the fact that they are not drilled or mounted. I am just looking for further information on them, if anyone has anything or knows of someone I could reach out to. Although I may not be wanting to sell these skis after learning their story, I would also be interested in getting them appraised if anyone has recommendations on that. Thank you all!
