I do not show a T-107 in my new gas pump identification book, but I do show a T-106. G&B called this pump the "Star Salesman," and it was introduced in 1930. The frame on the T-106 is also exposed. Since yours is a procelain pump, and appears to have been made especially for Sohio, possibly G&B labeled it the T-107. Assuming it is the same as the 106 I have some sales literature on it. If you are interested in the literature or my gas pump book, please email me at: jhsim@swbell.net
