Frank Hollenbeck was plant supt. at Baker when they moved to Batavia after the fire in Syracuse, William Baker being ill with TB. BG&FCo. built a boxlock gun of essentially a Hollenbeck design but with the narrower Baker barrel lug. They were often marked on the side Batavia Hammerless, but I've seen more of them marked New Era with no mention of Baker or Batavia. They are pretty much a footnote in American double gun history.
