Sinclair Traveller Una
The Sinclair Traveller Una is a British-made plate camera from the early 20th century, produced by James A. Sinclair of London for field and travel photography. It was sold as a hand-built, premium-tier instrument aimed at advanced amateurs and professionals working on glass plates and cut film.
Sales data for the Traveller Una is extremely thin: a single recorded UK auction hammer result from December 2009 stands at £9,000, which reflects wholesale saleroom pricing rather than dealer retail. With only one data point, today's value is best treated as indicative — what a Traveller Una sells for in 2026 will depend heavily on completeness, originality and condition rather than any reliable published median.

Frequently asked questions
What is a Sinclair Traveller Una worth today?
Based on the only verified UK auction record in our data, a Traveller Una achieved a hammer price of £9,000, but with just one sale this should be read as a reference point rather than a firm market value.
How much does a Sinclair Traveller Una sell for at auction?
The single tracked saleroom result is £9,000 hammer; actual price on any given example will move with condition, originality of the lens and plate holders, and the presence of the original case.
Why is the Traveller Una's price so high compared to other plate cameras?
Sinclair Una-series cameras were hand-built in small numbers in London as high-end field instruments, and survival rates are low, which keeps values for clean, complete examples well above generic plate cameras of the same era.
