Side B MCA 355-W4. The four sides run MCA 354, 355, 356 and 357. MCA2-10003 is the original US catalogue number for the 1973 double album, confirmed by contemporary MCA advertising.
W4 is a later lacquer revision within the original-release-era pressing history and does not by itself establish a first pressing. No plant assigned from MCA 355-W4 alone — Gloversville and Pinckneyville examples are both documented, with additional plant marks.
