“Condensed Comstock was introduced by Inland in 1905, but patented in the name of William A. Schraubstadter in 1908. It has no lowercase, but the design is more contemporary. Monotype has copied both typefaces, but Monotype Comstock Condensed is in 18-point only, without figures.” [McGrew 1993]
The face shown by Photo-Lettering as Comstock Condensed (with lowercase) [PLINC One Liner 1971] is based on Franklin Gothic and was previously shown as Franklin (condensed) Contour [PLINC 1960]. The face shown by Berthold with Facsimile Fonts credits as Comstock Condensed (with lowercase) is a copy of Filmotype Quebec [Berthold 1974].
