I know nothing about BMXs except some years ago my cousin asked me to look out for a Raleigh Burner and or a Bob Harro so hopefully this is a bit of cosmic ordering?
A bit of research leads me to believe it’s basically a Mk 1 gussetless Raleigh Burner with low end components made in the dying years of Raleigh (1989?). They seem to have been made from new old stock parts eg the frame number points to Nottingham June 1984. (Frame number NH4029558) They are said on a few sites to have been made for ‘Armstrong’ - who? and also to have been made to compete with cheap imports which doesn’t actually make sense. A bit more research shows that Armstrong was a vintage marque owned by Tube Industries (along with Triumph Hercules and of course Raleigh etc.) so it makes a bit more sense that TI Raleigh used an old marque they owned. Would it be a travesty to convert it to a replica Mk 1 burner? Can anyone chip in to tell me I’m barking up the wrong tree or any other information on this model please?
