History of Kosmos 250 MX
I'm featuring a Kosmos MX model in my classic camera section of Classic Dirt Bike and know nothing about the marque, can you help with even basic information?

At present I have no further information on the marque. If you would care to share the results of your research I would greatly appreciate it.
Happy to do that - the request arose as I was researching a feature for the magazine I edit - Classic Dirt Bike - our archive goes back over 100 years and part of it includes the Nick Nicholls' collection, Nick was a top motorcycle sports photographer for 30 years or so and would attend such shows as the Dirt Bike Show. Looking through his images for my double page spread archive pic 'Classic camera' the Kosmos caught my eye.
The info with the pic is generally an extended caption of about 100 words and the feature is popular.
