I checked my copy of the 1928 catalog. The only oversized pen listed is the grecian border, model 766A, described as "Oversize barrel; No. 6 nib." There is a notation above the grecian border pens that reads "Eversharps to match, Nos. 714, J414, 14 and 114MW." The oversize pencil was model number J414.
useful info.
