Sure. The information was hard to find; most books on swedish glass omit Björkshult altogether due to its limited scope of production ('blown, cut, handcrafted animals') but :idea: Bill Geary's "Scandinavian Glass - Creative Energies" has the answer.
Björkshult never survived the breakup of Royal Krona group and was closed in 1978.
The company was started in 1892, went through a bad patch in the 30s. Designers there were Ragnar Johansson {1940s}, Hans-Christian Wagner {1957-76} Margareta Schlyter-Stiernstedt {1953-68} and Carl-Einar Borgström {1950s-end}
