4087 3" Vertical Boiler/Avon Engine Steam Plant with Whistle.
Teaming up the Avon engine to the 3" Vertical boiler is ideal for those who want a longer steaming time over the Clyde, while loosing only a small amount of power.
The 3" boiler Avon combination will power boats up to 1100 mm at scale speed.
For smaller boats the performance is electrifying.
