No. 10 is the old 18th hole at Stockholms Golf Klubb.
As for the architect, there's no evidence of Colt having designed it.
Here's a summary written by the Swedish architect Peter Fjällman:
The first layout for an eighteen hole course at Kevinge was made by Jochum Beck –Friis but was soon rejected and J Nicholson from Hawtree and Taylor was called upon. But the board was not satisfied with the suggestions so more experts came to the site. A German architect , Emil Schultz , who at the time worked with B von Limburger made a plan and also J.S.F Morrison, an associate of H. Colt visited the site and presented a plan. But the committee were not satisfied so they started to make their own plans and Sundblom had a big influence. Finally “suggestion “ nr 12 was approved by the board and work stated on the new course.
We may assume that the final routing was a compromise of all the different suggestions and Sundblom probably was the man behind the mix. Sundblom went over to England to negotiate with contactors and seed merchants. During these business related negotiations, Sundblom had the opportunity to visit and study the classical courses of the United Kingdom. Finally the contract to build the course went to Carter & Co and Fred Smith and George Maywood came over to Stockholm. ( G Maywood stayed as the greenkeeper up to 1938 ).
In the autumn of 1932 the course was open for the members and the initial game was played between Edward, the Prince of Wales and the Swedish Crown Prince, Gustav VI Adolf.
