The attachment on the front of the magic lantern is <link ref="tec3006">Münsterberg’s apparatus for mixing colors by the combination of colored gelatine papers</link>. The papers were slipped into place like lenses, being mounted on levers. The same device is shown on <link ref="lit8140" page="p0004s0002" mk="0.4756/0.7425">another photo</link> from Münsterberg, 1893 or see the <link ref="tec3121">related experiment</link> on its own.VL Technology
