DOOM II: Hell on Earth (v1.666) (US, DOS, 04-10076)
The disc surface is a very nice looking matte print unlike many later reduced cost reprints with v1.7 and beyond, so I'm assuming this is from the first printing. The checksum it produces is unknown to Redump.
Unfortunately, this was a loose disc, so no additional scans can be provided. The disc's readable surface is pretty badly scratched, so I'm glad it produced an error-free dump. .aaruf format, of course.
