That is a beauty.
The closest thing I can find is the Brunswick Rochester circa 1912. The only difference I can see is that it doesn't have the moulding where the leg meets the vertical edge of the rails. I wonder if it has been re-finished and that moulding used to hide the joint? Aside from that, everything looks bang-on. Even the bevel at the foot of the leg matches. Also consider that custom orders were common. At that time, it was almost normal for a customer request minor (and major) modifications to suit their needs.
The other items in your photos are old scoring devices. I am not exactly sure what the flat board scorer is for, but it is definitely for scoring. The other one that is a wire with beads usually hung from the ceiling above the pool tables in pool halls and is used to score number of games won, among other things. It is where the billiard term on the wire came from (and some others as well):
The Brunswick Rochester billiard table was made between 1906 and 1924 (so it was obviously quite popular to be in production for almost 20 years).
The Brunswick Balke Collender Rochester model was made as an "improved Pfister" (The Pfister was an older model with similar style legs, which had more ornamentation).
There are a couple on eBay right now selling for between $5000 and $8000. A google search finds them easily.
Here is a technical description of the Brunswick Rochester billiard table from the 1912 Carom and Pocket Tables Catalog from the Brunswick-Balke-Collender Company:
The [Brunswick Balke Collender] Rochester pocket billiards table is a recent production and a modification of the celebrated Pfister style which is thoroughly well known through being represented in a majority of the largest and finest billiard rooms of the United States. Inasmuch as many judges of pronounced ability favor designs in furniture which are absolutely devoid of carved ornamentations or mouldings, we have adopted this feature in the Rochester, which depends entirely on the highly polished plain surfaces, gracefully sweeping lines and striking originality which puts it in a class by itself as one of the most artistic billiard tables ever produced. Design patent awarded January 1, 1895. Produced under various patents granted from 1892 to 1905.
Wood and Finish: Furnished in either quarter sawed oak or handsomely figured Mahogany. The oak is finished in our No. 6 medium or golden color, and the Mahogany in our regular No. 2 stock color and in what is known as an egg shell gloss, which means that after being given the ordinary cabinet finish, it is hand rubbed to a dull polish which can be more easily kept clean than any other furniture finish.
Construction: The heavy o.g. framework of body is built up in what is technically known as compound construction. That is, various kinds of woods tongued and grooved together and double cross veneered on the outside, the outer veneer being handsomely figured oak or mahogany. The legs are built up in the same way. This table is made in sections and can be taken apart for shipment. Double cross stretchers 1 1/4" thick x 9" wide countersunk into reinforcing blocks 8x9" and held in place by heavy iron frame bolt, making a rigid bridge construction. Long stretchers 1 1/4" thick x 5 1/2" .

The wood construction all of first quality, cabinet made and put together in a most thorough manner. All joints made close and secure and all mitres absolutely accurate. Glued up joints are tongued and grooved, strongly doweled and glued or screwed firmly together. All corners and edges made perfectly smooth and true.
Cushion Rails: 4" x 2" thick, compound construction built up of various kinds of hardwoods of different grain, double cross veneered. Plain solid corner blocks covering joint bolt heads.

These cushions are made in our own rubber plant at Muskegon, Michigan, from a secret formula which is used exclusively by us. Our guarantee as to their accuracy of angle, speed and durability is evidenced by the nameplate countersunk in the top of the cushion rail.
