I'm pretty sure that's a variant of the Almquist Shell
You would be correct. All of the BSDs and some GNU/Linux distributions use Almquist for sh if not using a symlink to bash or dash.
In fact, the first release of Slackware in 1993 had sh as a symlink to bash.
I'm looking at the source code for the Bourne shell as included with UNIX SVR4 (circa 1988) and it's obvious that the version which Sun Microsystems/Oracle shipped with Solaris under the CDDL is a direct decedent.
The license on the source code for the Bourne shell shipped with SVR4 clearly states:
"THIS IS UNPUBLISHED PROPRIETARY SOURCE CODE OF AT&T"
