1936; the house doesn't seem to have changed since then:

Here it is just a tad closer, also 1936:

This is the March 30, 1925, building permit for 344 S. Muirfield:

After I found the BP, I thought, "OK, so who was Lloyd K. Hillman?" It turns out he lived from
1889 to 1966.
Here he is in the 1942 LACD:

This is his first appearance at 344 S. Muirfield:

Here's where I ran into quite a coincidence. Before his auto businesses at 507 S. Flower, Hillman worked here:

March 8, 1917,
Los Angeles Herald @
CDNC
This is 526 S. Flower (c. 1916), which is now part of the Central Library property:

CHS-5790 @
USCDL
And 526 S. Flower is where the nephew of the
Los Angeles Times' Harry Chandler, Ralph Chandler, and his friend,
Charles Wellington Rand, had their auto business (they sold ALCOs until they were no longer made). Rand, you may
recall, built and later committed suicide in the
Baldwin Hills Oil Field House (aka the Rand-Cone House):
1917 LACD
In fact, Hillman had been Rand and Chandler's foreman as early as 1912, when their business was at
1246 S. Flower.
Hillman probably knew all about Rand and his troubles, as well as lots of interesting Chandler family info:

P.S. Thank you very much
JMR for looking around for the fairy-tale house; what you discovered is very interesting!
