Great! So now we just need Chopper's ad and we're there.
Below is not an advert but is a piece of copy from the 1984 Dawes brochure that claims that the Dawes Ranger is "The first British made cycle of its type." A claim that contradicts the May 1982 opinion of the Dawes sales director in reference to the Cleland design that "We are aware of your interest in your type of cycle in the USA..." If despite the separate lineage of the Cleland, it is viewed as an "All Terrain Bicycle", then The Ranger cannot be "The first British made cycle of its type." In fact British made US style mountain bikes were also made by Chas Roberts and Tony Oliver as early as 1981.
One interesting aside is the story of how I came by the 1984 Dawes brochure. It was given to me by Regent Cycles in Kentish Town, London in March 1984. At the time expecting their first delivery of Dawes Rangers in April 1984. A delivery that in fact was so delayed that I had already test hired and ordered an F.W. Evans ATB before any arrived in any of the many London bike shops that I visited. Interestingly the inclusion of the Ranger into the brochure appears to have been hurried in that despite the page one billing, the Ranger is not shown on the cover nor on the chart of model specifications.
The fact that the Ranger did not appear in the London bike shops I visited does not in itself mean that It did not appear earlier elsewhere. And so it could have in theory preceded the availability of the F.W. Evans. But speculation is not proof.
At the time that the 1984 catalogue was printed it is highly unlikely that Dawes knew anything about the production plans of other UK companies. So the claim that the Ranger will be "The first British made cycle of its type." in pure speculation based on the belief that they are the only British mass producer intending the 1984 launch of a an "All Terrain Bicycle".
It was to be the Evans derived Saracen ATB that became Britains best selling mountain bike. However, this was probably more due to the better design, publicity and marketing than the date that the competing brands first appeared in the shops.
Had Dawes, as promised, consulted Geoff Apps, then they would have definitely designed a better bike. This is because, of all the all early UK ATB manufacturers only Apps had any serious experience of designing and building and riding off-road bikes. All others played safe by copying the US Ritchey design.
