Missing one red teardrop prism on one lamp. The flash glass is crackling under the rim and near the base. You can barely see it in pic 5 and more clearly when you disassemble it, shown in pic 13. The lamps measure approximately: 22.5" Tall 7.5" Wide.
These are most likely made by EF & EF Industries in the 1970s. However, swag lamps were less often marked than desk lamps, and these do not have a company mark. The glass is flash/painted glass, not colored.
