official · M6 specifications: Leica Camera AG (M6 reissue datasheet, PDF) · accessed 2026-07-10

“Dimensions (width x height x depth) approx. 138.6 mm ... Weight approx. 575 g. Figures are from Leica's current M6 reissue datasheet; the original 1984 manual contains no spec table, so we cite the reissue with that caveat.”

official · K1000 specifications: Wikipedia (figures consistent with widely-cited manual dimensions; original manual PDFs at butkus.org/cameramanuals.org/ManualsLib are scanned images with no extractable text, and no official Pentax/Ricoh museum spec page could be located) · accessed 2026-07-10

“It is 91.4 millimetres (3.6 inches) tall, 143 mm (5.6 in) wide, and 48 mm (1.9 in) deep, and weighs 620 grams (21.9 ounces).”

M6 dimensions carry medium confidence (archived-source caveat on its fit page).

K1000 dimensions carry medium confidence (archived-source caveat on its fit page).
