You're welcome for the coronet info.
Some friends, however, chided me for not including the Brunswick brand coronet used on its pins, pinsetters, scoring tables, strike lights, bowling balls, bowling shoes, et cetera. Other divisions of the company include Brunswick Boat Group, Life Fitness, and Mercury Marine; but none of them bear the coronet logo. Brunswick also made school furniture in the mid-20th century which included the popular pastel-colored shell chairs.
While I found out that John Moses Brunswick opened his manufacturing company in 1845 and entered the emergent bowling business in the 1880s I couldn't find when the coronet was first used in the company's logo; however a local bowling alley, outfitted with Brunswick equipment when it was new in 1962, employed it while the furniture ad from 1956 (shown below) did not. In researching Brunswick Corporation information I actually discovered that it will be selling its bowling business to a competitor, Bowlmor AMF (whose pins have the double stripes instead of the coronet), which is scheduled to close at the end of next month; so that may very well be the end of the Brunswick coronet.
Below are some photos revealing the use of the Brunswick coronet (For you, Dave and Shelley):
(I realize the information about corporate coronet symbolism and Brunsick information is better suited for the Household forum; although I thought it was germane to the originator's comments about the use of crowns in corporate symbolism which he felt was limited to the '50s and '60s. This will be my last addition of information to this thread.)
