Stockholm lock Stockholm lock

Model of the Stockholm lock named Slussen, built in 1761. In the Jonas Norberg's directory of 1779 described as "Model of Slussen here in Stockholm. It had not been possible to do this model, which was completed in 1761, long after Slussen had finished, to the most accurate one that would be needed in the future, if not the undersigned who during the time of the building of the lock was by late Mr. Commerce Council Polhem, by him trusted to always be present at the lock work during the busy time, from the time the pit was finished dredged until the whole of the lock framework hung over it, was completed and immersed in its place, when at that time nothing unpleasant obstacle could be practiced under the bottom of the lock. At this time there was a good opportunity to get to know each pin and screw in this form which now is far below ground and water: One of Mr. Sluss Inspector Kiihlberg made drawing of Slussbotten, in comparison with my own observations, has even more put the undersigned in order, to complete an in all parts reliable model. This is so arguably stated that if any deficiency in the future would appear on Slussen's sides or underwater, you must certainly be able to retrieve the same place on Models, and according to the specified scale, guide themselves in the execution of the repair.".
