Take a look if you would at Q20504518. It is an instance of enterprise, factory, brand and trademark - and all of this is unacceptable for radiomuseum id property. No, it must also be a business. This is too restrictive. Some radiomuseum entries are not businesses at all - they are brands/trademarks owned by different entities. Or the communist-block establishments. This restrictive constraint should be broadened. Retired electrician (talk) 13:14, 14 October 2023 (UTC)[reply]
