I particularly like the reference to "Huntzinger" with a "t" and the fact that Hardy owned the building that Hunzinger was in. There is a resemblance between their work - see the Hardy chair
here.Another article I ran into while looking for more on Hardy is this:
one. It talks of a worker's strike and names many famous makers impacted: Pottier & Stymus, Herter, (Hardy), Roux, Kilian, Schrenkeisen, "Kemble and Cabers" (I assume was Kimbel and Cabus), Marcotte. Interesting reading these old accounts.
