I like Belgian bikes and Belgian swap meets.

Ran into Headbadge Man again last week at another event, which helped me remember I had those pictures.
I think you'll find the cranks to be HERMESSE, more info on them here:

EKLA frame parts were widely used in the fifties. In Belgium and Holland, but also in the UK. The EDCO-MANAL combination for the front wheel is also something I have come across more often.
My impression is that the number of actual bicycle manufacturers in Belgium is limited, compared the the huge number of different bicycle brands.
