For the period 1832 to 1918 boundary details below are nominal, and for the period 1918 to 1950 they are those applicable in 1918.
For the 1708 (first) general election and every subsequent election of the Parliament of Great Britain the Dumbartonshire constituency consisted of the county of Dumbarton minus the burgh of Dumbarton, which was a component of the Clyde Burghs constituency.
Nominally, the constituency had the same boundaries for the 1832 general election, but the burgh of Dumbarton was now a component of Kilmarnock Burghs. 1832 boundaries were used also in all general elections up to December 1910.
For the 1918 general election the constituency was defined as covering the county of Dunbarton minus the burghs of Dumbarton and Clydebank, which comprised Dumbarton Burghs. 1918 boundaries were used also in all general elections up to 1945.[6]
A petition was lodged in this election, against Stirling, but was later withdrawn after he decided not to defend his claim to the seat, allowing Smollett to be declared duly elected.
