I've been looking for a cheap frame suitable to build up into a fixed wheel
bike. I've been given an old Kojima Condor with downtube shifters, which I
know nothing about. The frame is marked 'Tange 900' double butted. I think
it’s a lugged steel frame. Does anyone here know if this is a reasonable
frame to dress up into a fixed wheel bike? I've googled but can't find much
info. The other bits of this bike show signs of neglect so I'm thinking if I
start with this frame it will need to be cleaned up, repainted and pretty
well have a lot of work done.

I want to use a fixed wheel bike for fun and training but also as a build
project to learn more about how to do assembly and get some basic know how.

Any help about the frame is welcome.

There is one essential and one desirable:

Essential: horizontal dropouts.

Desirable: either a high bottom bracket or slightly shorter cranks.
