Mentor Goltz & Breutmann Mentor Compur Reflex
The Mentor Compur Reflex is a German medium-format SLR produced by Goltz & Breutmann of Dresden, fitted with a Compur leaf shutter rather than the focal-plane shutter used on the maker's larger reflex models. It is an early- to mid-twentieth-century plate/roll-film camera aimed at advanced amateurs and professionals working at waist level through a reflex viewing hood.
Auction data for this model is thin: a single hammer result of £62 at a UK saleroom in June 2025 is the only recorded sale, so a meaningful price range cannot be quoted today. Buyers asking what a Mentor Compur Reflex is worth should treat that figure as indicative wholesale value at auction (commission excluded) rather than a settled market price, and condition of the bellows, shutter and reflex mirror will materially affect what any individual example sells for.

Frequently asked questions
What is a Mentor Compur Reflex worth today?
Only one UK auction hammer result is on record — £62 in June 2025 — so a reliable market value cannot be stated; price will depend heavily on shutter function and bellows condition.
How much does a Mentor Compur Reflex sell for at auction?
The single recorded saleroom result is £62, achieved in 2025; with so little data, individual examples may sell for more or less depending on completeness and working order.
Is the Mentor Compur Reflex a usable camera?
It can be usable if the Compur shutter fires accurately and the bellows are light-tight, but film and plate-holder availability for early German reflex formats should be confirmed before purchase.
