In June 2010, with the roof and two walls removed, the engine basked in the sunshine for the first time in 85 years.

Following disconnection of plumbing and accessories, the engine was raised off of its foundation and supported by blocks.  The power cylinder is to the left in the photo.  The compressor cylinder is to the right.

The bright sunshine highlights details of the power cylinder head.

Here is a detail of the power cylinder and the flywheel.  The engine is throttle governed. Note that the flywheel has pockets cast in the rim for barring over the engine using a lever and fulcrum, which have already been removed in this photo.

Now that the building was completely removed, it was time to move the engine off of its foundation.
