If you'd consider a real project, I also have a very small adult ladies' frame from about 1894. Very early. It's not a complete bike, but I collected enough parts to start a project. The frame is already stripped and straightened. To make a safe rider, the frame probably still needs annealing and/or reinforcement. Those early drop frames had weak geometry, and this one needed a lot of straightening. I would have to take inventory of what all I have for it. I know there is the frame, a fork, bottom bracket, seat post, and a suitable chain wheel. It could be a start.
