A 3 in. wide Triplex.

Notes:
The Prosch Duplex and Prosch Triplex do not appear to have been advertised together - once the Triplex was developed, the Duplex was apparently obsolete.
The G. Gennert 1895 catalog (Descriptive Catalogue of Photographic Apparatus and Supplies, G.
Gennert (New York, NY), dated Jan. 1, 1895, p.30) states that the
Prosch
Athlete Shutter is an alteration of the
Triplex
Shutter, which alteration may be had for $5.00 over the
price of the Triplex.
