I've read that, but I'd like to know more about where they got it. First, there is absolutely no S. C. Miller I can find associated with any tool business, nor a Carl Miller. I find several California Tool Company listings, but one in the mid 1800's and another (parallel timeline with that stated for CTC by Vanatta) but located in Sacramento. The CTC we are concerned with doesn't start showing up in searches until the 1960's. Based on the tools, it obviously existed but I cannot find it anywhere.......business registrations, city directories, newspapers, ancestry, etc. I did find a few WWII draft cards where the draftees claim employment at CTC, even one with the last name Miller.
Further, Alphonse is listed as a "Tool Maker" or "Tool Manufacturer" in his voter registrations in 1924, 26, 36, 38, 40, 42, and 44. The missing intermittent voter registration years absent in that list didn't record occupations. In the 1940 Census, he's listed as a "Tool Maker" "At Home." Meanwhile, his son Henry J. Plomb is listed throughout those years as either an "Assistant Tool Maker" or a "Tool Makers Helper" and always at the same address as his father. In 1930 the Census states he (Henry) is a Tool Mfg. in the Automotive industry and the 1930 voter reg. lists him as a machinist.
In 1913/14 LA City Directories, Alphonse appears to have his facility on his property (home) at 7674 Maie Ave. In those directories he's listed as a Tool Manufacturer at 7674 1/2 Maie Ave. I don't find anything at all prior to 1913. The earliest they show up in newspapers (search: "Plomb Tool" is July of 1915. Edit: I just found him as a tool maker in the 1910 (first appearance in the LA Directory) directory at 1658 Long Beach
Since we're on the topic, Jacob Weninger is also strange. He was born in 1891, which means Alphonse (at the age of 36, with a 6th grade education) and Charles went into business with a 16 yr. old, 8th grade educated kid? His naturalization papers do note his occupation as a tool maker. He's listed in voter records for 1922, 24, 30, 36, 42 and 44 as a Tool Maker. 1920 census: tool maker; 1930 census: Superintendent at "Tool Co"; 1940 census: Tool Maker "salaried private work" I also found Jacob listed in the 1910 LA Directory, also his first appearance as a tool maker. In 1909 he's listed as a "Wire Worker"
I don't know, but some stuff is not adding up.............
Edit: Weninger's Naturalization application is attached showing his age and occupation. Also, I tried to zoom in to see the tool manufacturer listed in Weninger's 1920 Census, and that screenshot is attached (Yellow Line is Weninger). It sure as hell doesn't look like "Plomb" though.....
