Guilleminot Detective Camera
The Guilleminot Detective Camera is an early plate camera from the French manufacturer Guilleminot, produced in the late 19th century when so-called detective cameras were designed to be used discreetly. It is a collector-grade item rather than a working photographic tool, and survives today mainly in the hands of specialist collectors of early apparatus.
Public UK auction data for the Guilleminot Detective Camera is extremely thin: a single recorded hammer result of £800 from November 2015, achieved at saleroom level and excluding buyer's and seller's commission. With only one data point on file, it is not possible to give a reliable price range or median for what a Guilleminot Detective Camera is worth today in 2026, and recent value will depend heavily on completeness, originality and condition.

Frequently asked questions
What is a Guilleminot Detective Camera worth at UK auction?
Only one hammer price is on file — £800 in November 2015 — so a current market value cannot be quoted with confidence; comparable early detective cameras from minor French makers typically trade as condition-driven collector pieces.
How much does a Guilleminot Detective Camera sell for today?
There is insufficient recent sales data to state a reliable today's price; the only logged UK auction result is £800, and any current sale price would depend on condition, completeness of plate holders, and bidder interest on the day.
Is the Guilleminot Detective Camera a usable camera or a collectable?
It is firmly a collector's item: plate film and service support are not commercially available, so its value is driven by historical and display interest rather than photographic use.
