Answering myself. Found a youtube video on the two triple expansion steam engines in SS Shieldhall. Seem very similar to those in SS Tarmo #sstarmo

Still looking for details on the boilers.

The ship – Steamship Shieldhall

Very cool. She is one of the largest still operating piston engine steamships in the world!

Anyone with more details on the boilers and engines??
