1880 is when L.C. Smith bought into the Baker guns. L.C. Smith's brother Leroy was working for Baker before 1880 and Leroy asked him for assistance in the Baker gun company and that is when L.C. bought into them. In 1883, Baker, Leroy and a few others left to go to Ithaca and started the Ithaca gun company along with George Livermore who was L.C.'s and Leroy's brother-in-law. Fascinating in that George became President and stayed on into his 90's and how other family members also helped. It was either Leroy's son or George's son who developed the Ithaca Model 37. It has been a while since I read it and can't remember which one but think it was Leroy's son.
Baker left Ithaca and he along with his brother went back and made their own guns.
