It was trying to find out about an Elswick Hopper that got me onto this forum. It was a very cool old bike, 1957 vintage or so, but is long gone now.
That bike was a Vampire model and had some of the coolest decals and graphics on it of any bike I've ever seen. Classic 50's British stuff.
I sold it to some guy who told me he was interested in starting a small EH museum in Britain. Maybe that was just a story. But he did pay me
to ship it to England.
This was at least 15 years ago and I have since searched the net about this brand. Not much info on them unfortunately.
