ON MY WORKBENCH. Slow and fiddly progress on the Andreyev. Although there's no cab turret on the published diagrams, photos show a late-steam type enclosed turret ahead of the spectacle plate. The first picture shows five turret valves installed in the spectacle plate.


Next up, the cab roof. There are side overhangs above each door, as the plan indicates. A rear view photograph suggests these were later additions.


The cab has many external features in common with the P36, which makes the modeling somewhat simpler as numerous semi-legal Soviet era and completely-legal contemporary era photos of those exist. (Some of the real things are in preservation, but it's a long way to Minsk or Piter let alone Ulanbataar.)
