While looking for pictures of the Central Manufacturing District, I found this one titled "Kantzinger [sic] Building in Downtown Los Angeles, 1934". According to the attached Examiner clipping dated September 1, 1934, "This three-story building in the central manufacturing district has just been acquired by the Edward Katzinger Company, Chicago, makers of bakery equipment and tinware."

I couldn't find an address, and after I'd spent a while looking around the area in the Googlemobile, I decided that it had probably been demolished along with so many of the other buildings. Then, while checking out
GW's possible chapel on the CMDT building, I spotted a pair of matching buildings at the bottom of the picture below:
Looking southeast over Central Manufacturing District Terminal (large white building with tower), located on Loma Vista between 48th and 49th (now Vernon). The six-story terminal was built in 1923; neighboring warehouses, closely clustered together, fill the frame. Photograph dated August 5, 1955.

I think that the two buildings were actually mirror images of each other, with one at either side of Loma Vista Avenue on District Boulevard. That's where I found them still standing, albeit in almost unrecognizable form.

The current addresses, as they appear on the buildings, are 4440 and 4500 District Boulevard. The property sites give build dates of 1925 and 1924 (they're certainly visible on the 1927 aerial that I posted recently). I think that the Kantzinger building was the one on the right (4440), which now seems to have parking on the first floor. Despite all the changes, the stonework at ground level still shows the shape of the original design.

To complete the intersection, this building once stood across the road from the two above, opposite Loma Vista Avenue. The picture is dated circa 1938.
This 1932 Canada Dry's Pacific Coast factory is located at 4501 District Boulevard in Vernon. The signs read "Canada Dry, the champagne of ginger ale." The brick and terracotta factory was replaced with a tilt-up concrete building.
