The boktjasker was built around 1875 near Wâlterswâld.[3] It was donated to the Netherlands Open Air Museum and re-erected there in 1928 as a static object. It was moved to a different site in the museum grounds in 2002 after spending some years in storage though still not operational because of its sheltered wind free location. The tjasker has four Common sails, which have a span of 6.90 metres (22 ft 8 in), making it the largest tjasker in the Netherlands. It is also one of only three boktjaskers left in the Netherlands. The mill can be visited during opening hours of the museum.[4][5]

The paaltjasker was built as an unemployment project of municipally Scheemda in 1992. It was erected near Midwolda to raise water into a small nature reserve. However this site proved problematic because of trees and shrubs and lack of public access so the mill was moved to Nieuw-Scheemda in 2001. It is now located close to drainage windmill De Dellen and is also operated by the volunteer miller of that mill. The tjasker has four Common sails, which have a span of 6.0 metres (19 ft 8 in). The mill is dismantled and stored indoors during the winter season and is owned by Molenstichting Oldambt.[8][9]
