Patented by Richard Smith for MacKellar, Smiths & Jordan on April 15, 1879. [Saxe 2015] Later also known as Relievo. Shown by Harrild & Sons c.1886. [Gray 1976] Sold by Lehmann as Umbra [Reichardt 2011].

The sample uses a modified ‘W’ for ‘V’ and might be inauthentic in this regard.

Not to be confused with the earlier Relievo (1878) and Miller & Richard’s Relievo (c. 1887).
