Comments
It appears that the large bell-shape design of the "Pomona" was to accommodate the use of a separate oil cup, however many were evidently installed without the cup. Broken specimens have been found with the oil cup actually molded out of the inner skirt (I believe these were found in Colorado).
Known areas of usage are near Telluride, CO; Bodie, CA; and Pomona/San Bernardino, CA. Two mint Pomonas were found in a Los Angeles area antique shop back in 1986---they were previously used as lamp shades on small table lamps! On the Bodie, CA line the Pomonas were only used on the top steep ridge poles (CD 162 Brookfields were used elsewhere). With two Pomonas used at each ridge point, it is estimated that as few as a couple of dozen Pomonas may have been installed on the 13 mile line. Here is a photo of one that survived: PicturePoster #213375100

I can add the following from an article on the Pomona line that appeared in the New York Times:
The New York Times
New York, NY, Sunday, August 25, 1895 vol. 44, no. 13,731, p. 20, col. 1-3
..............It is needless to say that great care, was taken with the pole line, or running track, for this lightning sprinter. There are, in reality, two transmission lines, one 13 3/4 miles to Pomona, and the other 28 ¾ miles to San Bernardino. Each is built of No. 7 B. & S. gauge of copper wire. At first it was intended to use insulators with oil in their curled rims, but the builders of the line fell back on a double-petticoat, flint glass form, which has answered admirably. As a matter of fact, the oil would not last long in the blistering sun of that region. The poles are Santa Cruz redwood, 23 feet long, and set 125 feet apart................

CD 162 Brookfields were used elsewhere.
Having walked this line, They also had 287 locke on it or used for replacements. Also found was a nice iron pin with cast lead threaded top.
