Description:Image: A Trade Card of John Sharpe (date unknown).
In the eighteenth and nineteenth century, many Birmingham gun manufacturers relied upon foreign export markets. Often, this could mean the sale of cheaper weapons as part of the 'triangular' system of the transatlantic slave trade. It is now extremely difficult to know if such manufacturers were even aware of the final destination of the products they made.
Note- Local Studies and History has a large collection of industrial 'trade cards', such as the one shown above.
