I want to know the answer to the following question:
In what span did Universal produce westerns with Kirby Grant?
All the background I'm provided with is that "By the early 1940s, the company was concentrating on lower-budget productions that were the company's main staple: westerns, melodramas, serials and sequels to the studio's horror pictures, the latter now solely B pictures.". Is that enough to answer the question?
Answer: no
