The Wolverhampton ones stopped around 67, I believe from googling around a bit.
http://classicvikingcycles.com/ Another site suggests that Roy Clements (the NI owner I presume) acquired the name around 1977, which predates this 1979 model.
I bought this bike to use it for a specific purpose. I kept on getting advised that if I couldn't spend £600 or whatever for a decent bike, that I should just do triathlons with what I have to hand. But that's a single speed bike, and after doing one hilly triathlon on it, I decided that I wanted gears. My Viking Vision has gears, and while it's not light, it doesn't weigh a freakin' ton

I went out on a group cycle and I was easily climbing hills seated while all around me (just regular people) were standing up - usually it's the other way around.
When I bought this bike, there was a Dawes being sold for the same price. it looked better and in better condition, but weighed much more. Which surprised me as when I met a guy riding a 531 tubed Dawes, it was impressively light even though it had mudguards and a carrier. I presume the Dawes I saw was a 'gaspipe' cheap model.
Today I saw a modern Viking sprint on sale for £100, less than twice what I paid for my vision. Look at that, I thought that it might have been a better option to quickly obtain gears. But when I lifted it, it weighed an astonishing amount. Which surprised me as I thought that 6061 aluminium wasn't that bad a material.
I really like the idea of 'classic' bikes and classic other things (I have some 1970s and 1980s guitars). But this bike I've just bought is in reality a cheap stopgap measure until I work out what I really want to do. I'm going to ride it out into the country tomorrow, so who knows what I'll learn then

But as of the moment, this bike seems to be fulfilling its purpose quite well. Even if it isn't historically interesting
