I'm in the process of working with a seller for a partial trade, partial cash purchase of this antique bike. I consulted a friend who is working on an antique bike exhibit for a local museum, I ran it by him and he gave the deal an enthusiastic stamp of approval.
It's British, the sprocket is made by Scott, but there is no badge or other identifying marks, which is common for a British bike. It looks very similar to the Engin bike pictured in the color ad below, but there are differences in the details. The guy I'm buying it from deals in British bikes and even he doesn't know who made this one, but if anyone would like to try to ID it, have at it! The wheels have a date of 3-18, the bike may be slightly earlier.
The first two photos are of the bike. We're sorting out a problem on the tires at the moment and it needs some cosmetic things like old pedals and the skirt guard lacing, but it is functional and with the tire fix, it will be rideable.
There is of course the option to eventually do a restoration, nickle plating and paint. Starting out I'm going to enjoy it unrestored for a while, I kind of like the way it shows it's history. I can decide later if I want to restore over time, and if restoring would be better to ensure it's long-term survival.
The last photo is me in my Edwardian outfit, which I'll be wearing when I ride this bike at events. Pretty darn close to that lady in the ad!
