Leica M Prototype

{"overview":"The Leitz M Prototype refers to pre-production and experimental examples of the M-series 35mm rangefinder camera built by Leitz of Wetzlar. That spread reflects how much the specific prototype, its documentation, and its place in M-series development history matter: a well-documented, historically significant piece sells for many multiples of a more routine pre-series body, and today the ceiling of what one is worth is set almost entirely by provenance. Because these are hammer (wholesale) prices in the saleroom, retail and dealer asking figures for comparable pieces typically sit higher.","buying_guide":"Because no two prototypes are necessarily alike, buyers should insist on clear provenance, factory or archival documentation, and ideally a Leitz\/Leica factory record tying the serial number to a development programme. Inspect for later modifications, swapped top plates, or parts cannibalised from production M bodies, as these materially affect value.
