Algol-W compiler as used on MTS at NUMAC.  Found online at https://www.softwarepreservation.org/projects/ALGOL/source/algol_w/mts/d3.0/

Use MTS2strop and then 'qfilter' to generate canonical form after line-reconstruction.

Unfortunately the parser doesn't recognise all the extensions in this Algol so I can't
generate pretty HTML versions of the source files yet.
