Replacement knobs for a hob (DA7 Barnehurst/Bexleyheath)

4 metal replacement control knobs for a hob.
Bought for our indesit oven but they only fit upside down.
The flat part of the hole at the back is at the top/same end as the dot which lines up with the settings. Hope that makes sense.
Should fit a hob of some sort I think
Metal not plastic
Collection any time, can leave outside on our driveway if needed.
