Welcome Gabriel,
The Douglas Motorcycle Forum is an open Forum in that you do not need to be a member of any motorcycle club, just have an interest in Douglas motorcycles. So anyone that visits the Forum will see your post, and if they are registered with the Forum, can reply.
While the Forum is a completely separate entity from the London Douglas Motor Cycle Club (LDMCC), quite a few LDMCC members are registered and contribute to the posts. A few years ago the LDMCC did a article in their club magazine the New ConRod about how many export models were shipped out to the various countries based on the postwar factory dispatch records. It would take some digging to find the issue, but I do recall that quite a number (somewhere around fifty?) did go to South America.

Addendum 31Aug15. Estimate for number exported woefully inadequate. See subsequent post. -Doug
