Merkel(any of them) & Kettner were tied @ the hip. So if Kettner was retailing an upper rung sporting weapon, it was more than likely sourced from a Merkel source; almost synonymous..... Now Kettner did have a flock of mechanics and their specialty was probably maskin'....... But almost like the Kettner - Merkel connection, Kettner and A. Francotte were very chummy..... I guess the ledger is the only way to sort it...
