Good find/price on the spoon. Gerry at Hawk Cars makes the whole assembly but no idea on price.
The outer door handle chrome looks to be in very good condition, I'd be tempted to swap the parts out into a replacement door handle. It is possible to punch out the two (I think) pins that the hand pivots on to dismantle them, best done with a donor handle so you know what you're doing. Just make sure that the replacement plastic has it's three securing studs intact. I'm sure someone on here will have a spare lying around.
