Sinclair Una

The Sinclair Una is an early British-made plate camera produced by the London maker James A. Sinclair & Co. It was offered as a compact hand-and-stand camera in the early twentieth century, positioned at the premium end of the market alongside Sinclair's other tropical and precision models.

At recent UK auction, hammer prices for the Sinclair Una have ranged from roughly £120 to £650, with a median around £440 based on the limited sales on record. The most recent saleroom result in 2023 sat near the upper end at £438, suggesting the model still sells for solid money today when presented in clean, complete condition, though the small sample means value is highly condition- and completeness-dependent.
