I've read several places including a Charles Daly site that in 1919(one source gave 1910 but may have been a typo) that Henry Modell purchased S,D&G but most give that the successor to S,D&D was I. & S.D. Davega, which was founded in either 1878 or 1879. And in 1927 or 1928 Sloan's Sporting Goods purchased the trademark/tradename Charles Daly so any longarm post say 1928 with Charles Daly on it would have passed thru Sloan's Sporting Good's books.

Kind Regards,
