Though this near matching pair of sconces is unmarked, they were most certainly manufactured by the well-known Dutch company Philips. As similar models in frosted glass and (perforated) metal by the same manufacturer have been documented. Period1950-1959.
Nearly matching because one of them is a fraction larger and has a little bit different holder between the glass and wall (see pictures).
Each sconce with one small Edison screw (SES), (E17 14-17 mm) max 60 watt, the electric parts are in a good condition, approved to European standards.
Price for the set.
Dimensions: height 11.8 in. (30 cm), depth 4.3 in. (11 cm) and width 6.9 inches (17,5 cm).
