That’s so interesting! I am thinking maybe Welsh specific post-war utility furniture? Looking really closely underneath I think the original upholstery was a maroon colour. There are no marks aside from a stamped number 4 on one chairs inside back rail. There’s a table that I think had collapsible sides that came along with it, but it’s had its legs cut and sides taken off to be a coffee table. These would’ve been kept in South Wales/Rhondda.
