Hello Martin,

WB is Wavre Belgium allright. The numbers on the transformers are part numbers, there don't happen to be date codes (one or two letters, 3 numbers) on them as well? Otherwise my best guess is 1950's. Maybe schematic diagrams for later versions (GM... model numbers instead of 4 digits only) will be of use, if you can find them.
