Great start, but I have some nits to pick.
The site says guns of W.H. Baker and pictures a gun designed and produced well after he was dead. A gun he had little to nothing to do with the design of. Much more the gun of (?) Frank A. Hollenbeck's design.
The paragraphs under 1887 and 1889 are all wrong. The trigger-plate hammer gun first built by Syracuse Forging and Gun Co. was an A.C. McFarland design, Patent No. 370,966. The last W.H. Baker design gun to be manufactured was the Ithaca Gun Co.'s Baker Model hammer gun. Syracuse Forging & Gun Co. moved to Batavia, NY, in February 1889, and William H. Baker died of TB in the early morning hours of October 10, 1889. The company name was changed to Baker Gun & Forging Co. on April 2, 1890. The "Baker" in the name is the owner, Dr. Ellis L. Baker, the founder and President of the company, who controlled it.
