Can anyone identify this door handle please?

Morning all,

Our kitchen is about 8 years old now and whilst nearly all of it is holding up just fine, just one of the door handles has inexplicably gone all manky - bad lacquer perhaps.

Anyway, as the kitchen was fitted by the builders before we moved in, we have no idea what the make or name of any of the fittings are. Can anyone identify the handle please, and where to find it if it is still in production? Thanks!

Just gone and measured mine - they are 438mm long, 405mm between screw centres, the square end bits are 23mm wide. They are brushed nickel or stainless steel, I can't tell which.

Does that match anyone who has posted with the same in their house?
