Windows 3.0 build 48

A video claiming to show Windows 3.0 build 48 was posted to YouTube in June 2020. Aside from the version numbers, copyright dates of various programs and SDK Tools program group, this build appears identical to build 55.

It is apparent that the video aims to replicate the build shown by Craig Brockschmidt, the developer of the Windows 3.0 Calculator application, as it both uses the same color scheme and the version of Calculator matches the one in the shown picture. MicroVideos, the publisher of the video, has neither shared the build nor responded to requests for it, and hasn't been active since the video was posted, putting the legitimacy of this build into question.
