This is my first post on the forum, so with encouragement from Richard to respond here goes.............
Yes, as Grant says, the door handles are from the Standard series, the 8 & 10 HP of the fifties I believe, as for the bonnet hinges they are I think unique to the Bond, the closest I have ever seen are from the Morris Oxford MO series of about 1950/1 but even these are a bit shorter.
Use a decent chrome plating company for the hinges I reckon and have a look on Ebay or Standard 8/10 Owners Club for the door handles
