They are sister companies.
It's all very muddled, even after looking for corporate records. Red has an as-much-as-we-know summary in one of his recent blog entries. This is discussed in a couple of previous entries.
J. M. Bucheimer Co (Frederick, Maryland)
An old line company dating to the turn of the century (that other one) as a holster company. Bucheimer ended in the late 1980's, acknowledging guesswork because of our lack of official records.
Bucheimer-Clark Corp, 6314 S. Broadway, Los Angeles 3, California.
A merger of Bucheimer and the LA based Clark holster company - dating to about 1930 - incorporated in 1959. Dissolved in 1970 when both came under the Tandy corporation. The last B-C catalog we have is dated 1978.
Some of us consider B-C to have had a slightly higher quality product, in general, as also the Clark product line. Original owner Ed Clark patented a spring retention holster (Berns-Martin had to acknowledge the Clark patent). Both Ed and son Earl were prolific designers with Earl later working for Safariland. Bucheimer had some top designers - Kippen - on payroll too, but I'm a fan of Clark, so I'll emphasize them.
And then there were holsters marked Thompson, Thompson-Clark and Clark (Anaheim) using the B-C designs. Red was acquainted with Thompson as an LA company attempting inroads into the 70's police market. Then holsters from the other two have popped up recently. Dunno...
