If you ever visit Florence make time to see the Museo Galileo.
The lower telescope in the middle picture is the one that I based mine on. This was primarily because the dimensions and lenses were suitable to making a replica. The longer one has a 1330mm FL and I couldn't find a lens that was close to that. (The shorter one has a 980mm FL and 1000mm FLs are available). At nearly 1.5m length it's also a bit unwieldy.
The literature suggests that the upper scope was a research tool and may be the one he used to make observations for Siderius Nuncius since it is dated to 1609. The lower one is dated 1610 and is clearly a fancy version (leather wrapped with decorations). He may have sold some of the fancy ones and presented them to influential people to convince them of the validity of his work.
