Italic-only in 3 sizes (10, 12, 18pt) with swelled strokes and swash caps. Origin uncertain, but first known appearance is in Bruce’s March 1, 1870 supplement. Sold by AG für Schriftgießerei u. M. as Zirkularschrift. [Seemann]

No known digitization, but the lowercase is quite similar to Clifton Italic (used for sample).
