I have a brand new unused Mk1 locking door handle (part number 24A1140) with two driver's door escutcheons and one rubber seal. Comes with two keys.
This was purchased from Somerford in 2017, I forgot that I had it - then went to fit it and realised it's the wrong one for my car!
£35 including postage, or collection from Northampton. This item is also advertised on eBay so it may sell there first.
