340 N. Main Street. Plymouth was once known as the “Air Rifle Capital of the World” and it all started here: This building was originally the Markham Air Rifle Company. Markham started making BB Guns in 1886. The modern day BB gun was invented/developed here in Plymouth, MI by Markham (2 yrs prior to Daisy). Markham Air Rifle was the supplier of BB guns to one of the Nation’s largest toy companies. The demand for BB Guns became so popular that the Plymouth Iron Windmill company changed it’s name to Daisy and started making Air Rifles themselves. In 1916 Daisy Air Rifle acquired controlling interest and in 1928 Markham was renamed King Air Rifle. This structure is the largest commercial all brick building in Plymouth. Today this building now houses office space and has a restaurant on the first floor.
Additional info: Founder William F. “Philip” Markham also built the iconic white Victorian home that sits in the center of town across from Kellogg Park which is most known today as the “Wilcox House”.
