Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 194-195. See also the illustration and data in Matthias Nace Forney's July 1889 installment of his Catechism of the Locomotive in Railroad and Engineering Journal, Volume LXIII [63], No. 7 (July 1889), p. 335. (Thanks to Chris Hohl for his 5 July 2017 email noting the B-1's coal capacity and firebox heating surface area as well as for supplying the link to the information.) Works numbers were 2719-2720 in 1889.
Although the later Schenectady catalogue showed 110.3 sq ft (10.25 sq m), Locobase goes with the higher figure reported by Chris Hohl. It's likely that the 17.5 sq ft difference can be attributed to "water tubes" in the firebox, although the source does not say.
Rolling on an unusual wheel arrangement on any railroad, this pair of Forneys held on to their original numbers until the second decade of the 20th Century. Then they were renumbered three times in two years.
1003 was sold in March 1912 to J T Gardner. 1004 was renumbered three more times in 1912-1913 to 1304, 44, and 48. As the latter number, the 48 was sent to the scrapper in November 1913.
