Michel Mann specialised in the production of such pistols, as well as miniature cannon and small caskets, some of the last of which bear the signature of Conradt Mann, with whom he probably worked.
The largest group of his pistols on public display is in the Museo Poldi Pezzoli, Milan (cat. inv. no.s 922-931).
For an account of the work of Michel and Conradt Mann, see Claude Blair, The James A. de Rothschild Collection at Waddesdon Manor, Arms, Armour and Base-Metalwork, p.486. The mark on the barrel of lot.... appears together with Michel Mann's initials on a miniature cannon described on p.482
