Well, as Logan goes, this is a fairly small change. The annex entry was extended, though the front look and door layout was extended, and a new wing was added off the back of the temple Annex. This particular layout to the temple would remain in place for the next 30 years, marking the longest single span of un-altered temple for Logan so far.

Very nice. In the 30’s was also when it was first lit with floodlights.
