Possible Murphy windmill progress

After having stalled for many years, it looks as if work on rebuilding the Murphy windmill in Golden Gate Park has restarted.

My only evidence for this is a photo on flickr which is not positively identified, but does look as if it could be the Murphy windmill base, now sporting a new stage. It's a slightly strange way to be going about rebuilding a windmill - I would have thought that getting the uprights in first would have been far better, and that having the stage in place would stop you getting the necessary access to the base to make the body easy to build.
