Voynich’s Viennese Agency

[Hubert Dale]

Can I suggest “Mm Sliwinski + Stapinski”? I think there is a plus/ampersand before the capital S of the second name, connected by that upward diagonal stroke, and Mm would then be the plural abbreviation for M (Monsieur). So two individuals rather than a single person with a double-barrelled surname.

And Anton is quite right: it’s ‘plan’ and not ‘Man’.
