This is how the fork looked like up until about 1948. This is said to be Harry Snells bike that he used to win the world championships on in 1948. Could be true but it does have world championship stripes... Those might have been added later or it is later bike... Anyhow -this is a the earlier front fork:
And here Harry in the Swedish championships in 1947 showing the fork crown and the earlier forks totaly different "stance". The earlier forks all had a more sharp bend to them.
And here the 1951 catalog showing the later crown type - the one my bike has.
Conclusion = The ones with your type of fork crown is a short run made around 1949-50. Congratulations on a nice bike!
