Dear Jean - many thanks. In fact, I've discovered since my query that if you go to the Fronimo website, you'll find a "Pavan" font available for use. Also, if you download and install the Fronimo executable - even its demo package (which doesn't allow you to save your files) - you'll get several fonts which can be used. Orlando Lutes provide a package called LuteScribe which includes a font called LeRoy. This latter font is probably the closest to the font used in some early 17th century publications.
I'm not fully sure of the copyright issues with these fonts. For my own personal use, it doesn't matter. But I'm not sure about the legality of using these fonts in files made available, for example, on IMSLP.
