Build 34 is the earliest known build of Windows 95. It is mentioned in OLDSETUP.INF from later Chicago builds (e.g. 58s). The same file also mentions "M32 external release", so perhaps this is the build that was released to 40 ISVs in March 1993.
There is also a video of this build by George Wolfowitz. As the build remains to be leaked, the authenticity of the build in that video can't be confirmed, though it's considered pretty accurate in regards to other information available about early development of Chicago. Some screenshots were posted by betaguy224 but they were proven to be fake.
