This is a model of Scovill camera unknown in catalogs.  The best name for it so far is Unknown Scovill Blair-Utility-Type View Camera.  Three such cameras are known to me.  The first two to be found have Scovill stamps only (Serial No. 299 and 293), whereas the last one to be found has both Scovill and Jas. W. Queen, Philad'a, PA stamps (one of the Qween stamps partially obliterating a Scovill stamp.

     Serial No. 190 was obviously sold by Jas. W. Queen & Co., Philadelphia, PA, being so stamped twice on the top of the rear platform rail.  Queen & Co. was a supplier of photographic goods, including camera, most of which were sold as the manufacturer's product, but a few of which were presented in Queen & Co. catalogs as their own and given their own name.

      All three cameras are identical in form and finish, except that Serial No. 190 does not have the metal corner guards as have the others.  They share a number of features different from any other camera made by the Scovill Mfg. Co., it seems as if it couldn;t have been made by Scovill.

      The features unlike other Scovill products are:
1.  The platform rails have an L-shaped cross-section.  L-shaped rails very uncommon, and so far are only found in the L.M. Prince Utility View Camera, made by the Blair Camera Co, and in two variations of a utility-type camera marketed by Blair itself: the Blair Utility Camera Variation 1 and the Blair Utility Camera Variation 2,  Neither of the Blair variations generally show up sporting a Blair label, in spite of being present in Blair catalogs.  The only difference between what I take to be a Prince Utility and what I take to be the Blair Utility is that the Prince version has a hinged ground glass frame, whereas the Blair versions have Blair-style spring backs.

2.  These cameras all have downwards hinging ground glass frame, like many of Scovill's less-expensive models, such as the Waterbury View Cameras (4 variations), the Favorite View, and the New York View.  However, while the common Scovill models mentioned have very plain ground glass frame rails having square or rectangular cross-sections, the ground glass rails of this model start out with a 3/8" square cross-section, but then taper for an additional 3/16".  This appears identical to that found on the Rochester Optical Co. New Model Variation 1.0, an early ROC model, which suggests that the

3.  Their ground glass is secured not by inexpensive brads, or even quarter-round moldings, as used in some Scovill cameras, but by a flatter retaining molding which can nailed with brads to the frame by hand much easier than a quarter-round molding.  This detail is like that seen in the Samuel Peck & Co. (owned by Scovill) Stereo Camera Example 2, c.1880.  This feature may therefore indicate a rather early dry plate camera - i.e., early 1880's.

4.  Two of the three examples (s/n's 190 and 293) are sporting a circular, spring-loaded catch at the top of the rear standard engages a brad to hold the ground glass frame in place.  Brads on the long edges of  each plate holder are likewise engaged by the catch.  No other Scovill product has ever been found to have such a catch.  Rochester Optical Co. models often have circular catches.  In fact, the catches seen here are virtually indestinguishable from ROC catches.  That it appears on two examples means that it was manufactured that way, not just altered by the camera owner.  The third example (s/n 299) has a home-made clasp where a circular catch may have originally been,

5.  The rear standard has wooden blocks that slide through the L-shaped rails of the platform.  This is more like the Rochester Optical Co. New Model Var. 1.0 View and the Blair Camera Co. Utility View.

6.  The front and rear standard box joint construction is unlike the other Scovill cameras.  In trying to understand Scovill models, I have been comparing their front and rear standard constructions, where sometimes the box joints sit upon blocks of different heights and sometimes they don't.  When the research is finished, I will add a web page comparing them all, but, for now, these three cameras are different from all the other Scovill cameras I have ever owned.
